<h1 id="normal-mapping">Normal Mapping</h1>
|
||||
<p>W tej części będziemy dalej modyfikować shadery <strong>shader_5_tex</strong> poprzez implementację normal mappingu.</p>
|
||||
<p>Obliczenia dla map normalnych należy wykonywać w przestrzeni stycznych. Przestrzeń styczna jest wyliczana dla każdego punktu w obiekcie. Jej celem jest takie przekształcenie przestrzeni, żeby wektor normalny był wektorem jednostkowym (0,1,0).</p>
|
||||
<p>Do wyliczenia przestrzeni stycznej potrzebujemy dla każdego wierzchołka oprócz wektora normalnego wektor styczny i bistyczny (<em>tangent</em> i <em>bitangent</em>). Są one wyliczane przez bibliotekę <code>Assimp</code>.</p>

<ol type="1">
|

<li><p>Oblicz macierz <strong>TBN</strong>.</p>
|
||||
<p>Macierz <strong>TBN</strong> to macierz 3x3 wyznaczana przez wektory <em>tangent</em>, <em>bitangent</em> i <em>normal</em>, służy do przenoszenia wektorów z przestrzeni świata do przestrzeni stycznej.</p>
|
||||
<ol type="1">
|
||||
<li>W <strong>vertex shaderze</strong> przekrztałć wektory <code>vertexNormal</code>, <code>vertexTangent</code> i <code>vertexBitangent</code> do przestrzeni świata (przemnóż macierz modelu przez te wektory, tak jak to robiliśmy wcześniej z wektorem normalnym, z uwzględnieniem zmiennej w=0) i zapisz wyniki odpowiednio w zmiennych <code>normal</code>, <code>tangent</code> i <code>bitangent</code>.
|
||||
<ol type="1">
|
||||
<li>Stwórz macierz 3x3 TBN jako transpose(mat3(tangent, bitangent, normal)). Macierz transponujemy, aby szybko uzyskać jej odwrotność (możemy tak zrobić przy założeniu, ze jest ortogonalna).</li>

<ol type="1">
|

<li><p>Musimy przekształcić wektor światła (L) i wektor widoku (V) do przestrzeni stycznych. Zrobimy to w vertex shaderze. W tym celu przenieś potrzebne dane dotyczące światła i kamery (uniformy <code>lightPos</code> i <code>cameraPos</code>) z <strong>fragment shadera</strong> do <strong>vertex shadera.</strong></p></li>
|
||||
<li><p>Oblicz wektor <code>viewDir</code> jako znormalizowana różnice <code>cameraPos</code> i <code>worldPos</code> (tu jeszcze działamy w przestrzeni świata). Analogicznie oblicz <code>lightDir</code> jako różnicę <code>lightPos</code> i <code>worldPos</code></p></li>
|

<li><p>Przekształć wektory <code>viewDir</code> i <code>lightDir</code> do przestrzeni stycznej mnożąc je przez macierz <strong>TBN</strong>. Wynik zapisz w zmiennych <code>viewDirTS</code> i <code>lightDirTS</code> odpowiednio.</p></li>
|

<li><p>Przekaż <code>viewDirTS</code> i <code>lightDirTS</code> do fragment shadera. (zadeklaruj je jako zmienne <code>out</code>)</p>
|
||||
<blockquote>
|
||||
<p>(Sufiks TS oznacza tangent space. Ważne jest, aby oznaczać (np. dopisując coś do nazwy zmiennej) w jakiej przestrzeni znajdują się używane wektory, tak aby poprawnie wykonywać obliczenia. Trzeba zawsze zwracać uwagę na to, w jakiej przestrzeni działamy.)</p>

|

<ol type="1">
|
||||
<li>Nie potrzebujemy już we <strong>fragment shaderze</strong> informacji na temat pozycji fragmentu i wektora normalnego geometrii, skasuj wiec zmienne przekazujące te wektory pomiędzy shaderami.</li>
|
||||
<li>wektora <code>lightDir</code> powinniśmy użyć wektora <code>lightDirTS</code> (należy go dodatkowo znormalizować), a jako wektor widoku V powinniśmy użyć wektora <code>viewDirTS</code> (również należy go znormalizować). Jako wektora N użyj na razie wektora vec3(0,0,1).</li>

<p>Efekt finalny powinien wyglądać tak samo, jak przed jakąkolwiek zmianą. Następnym krokiem będzie wykorzystanie map normalnych.</p>

<h3 id="wykorzystaj-normalmapy">Wykorzystaj normalmapy</h3>
|

<ol type="1">
|
||||
<li>Chcemy wczytywać normalne z tekstury, w tym celu dodaj we <strong>fragment shaderze</strong> dodatkowy sampler do czytania map normalnych, nazwij go <code>normalSampler</code>. Pobierz z niego wektor normalny analogicznie, jak czytamy kolor zwykłej tekstury z samplera <code>textureSampler</code> i zapisz go w zmiennej <code>N</code>.
|

<ol start="2" type="1">
|

<li>Ponieważ w teksturze wartości są w przedziale <span class="math inline">\([0,1]\)</span>, musimy jeszcze przekształcić je do przedziału <span class="math inline">\([-1,1]\)</span>. W tym celu przemnóż wektor N przez 2 i odejmij 1. Na koniec warto jeszcze znormalizować wektor normalny, aby uniknąć błędów związanych z precyzja lub kompresja tekstury.</li>
|
||||
<li>Wczytaj pliki zawierające mapy normalnych w kodzie C++ W tym celu załaduj przy użyciu funkcji <code>Core::LoadTexture</code> mapy normalnych dla wszystkich modeli. Maja one taką samą nazwę jak zwykle tekstury, tyle że z suffiksem "_normals".</li>
|
||||
<li>Zmodyfikuj na koniec funkcje <code>drawObjectTexture</code>. Dodaj do niej nowy argument <code>GLuint normalmapId</code>, który będzie służył do przekazywania id tekstury zawierającej mapę normalnych. Przy użyciu funkcji <code>Core::SetActiveTexture</code> załaduj <code>normalmapId</code> jako <code>normalSampler</code> i ustaw jednostkę teksturowania nr 1. Argument odpowiadający za normalne w miejscach wywołania funkcji <code>drawObjectTexture</code>.</li>

<h3 id="zadanie">Zadanie</h3>
|
||||
<p>Ustaw mapy normalne do statku planety i księżyca (lub przynajmniej 3 obiektów, jeżeli rysujesz swoją scenę). Wykorzystaj multitexturing na statku, musisz w takim wypadku mieszać zarówno tekstury koloru i normalanych.</p>
|
||||
<h2 id="skybox">SkyBox</h2>
|
||||
<p>Cubemapy są specjalnym rodzajem tekstur. Zawieją one 6 tekstur, każda z niej odpowiada za inną ścianę sześcianu. Nie służy ona do teksturowania zwykłego sześcianu, pozwala ona bowiem próbkować po wektorze kierunku. To znaczy, możemy o tym myśleć jak o kostce, w której środku się znaleźliśmy, co obrazuje poniższy rysunek. W przeciwieństwie do zwykłych tekstur samplujemy ją nie za pomocą dwuwymiarowych współrzędnych UV, ale za pomocą wektora trójwymiarowego, który odpowiada kierunkowi promienia. <img src="./img/cubemaps_sampling.png" /> Jednym z zastosowań Cubemapy jest wyświetlanie skyboxa, czyli dalekiego tła dla sceny. Może to być na przykład rozgwieżdżone niebo z górami na horyzoncie albo obraz dalekiej galaktyki.</p>

# Normal Mapping
|
||||
|
||||
W tej części będziemy dalej modyfikować shadery **shader_5_tex** poprzez implementację normal mappingu.
|
||||
|
||||
Obliczenia dla map normalnych należy wykonywać w przestrzeni stycznych. Przestrzeń styczna jest wyliczana dla każdego punktu w obiekcie. Jej celem jest takie przekształcenie przestrzeni, żeby wektor normalny był wektorem jednostkowym (0,1,0).
|
||||
|
||||
Do wyliczenia przestrzeni stycznej potrzebujemy dla każdego wierzchołka oprócz wektora normalnego wektor styczny i bistyczny (*tangent* i *bitangent*). Są one wyliczane przez bibliotekę `Assimp`.
|
||||
|
||||
### Wykonaj kopię shaderów shader_4_tex.vert shader_4_tex.frag
|
||||
|
||||
### Przenieś obliczenia światła do przestrzeni stycznej.
|
||||
|
||||
1) Oblicz macierz **TBN**.
|
||||
|
||||
Macierz **TBN** to macierz 3x3 wyznaczana przez wektory *tangent*, *bitangent* i *normal*, służy do przenoszenia wektorów z przestrzeni świata do przestrzeni stycznej.
|
||||
|
||||
1. W **vertex shaderze** przekrztałć wektory `vertexNormal`, `vertexTangent` i `vertexBitangent` do przestrzeni świata (przemnóż macierz modelu przez te wektory, tak jak to robiliśmy wcześniej z wektorem normalnym, z uwzględnieniem zmiennej w=0) i zapisz wyniki odpowiednio w zmiennych `normal`, `tangent` i `bitangent`.
|
||||
1. Stwórz macierz 3x3 TBN jako transpose(mat3(tangent, bitangent, normal)). Macierz transponujemy, aby szybko uzyskać jej odwrotność (możemy tak zrobić przy założeniu, ze jest ortogonalna).
|
||||
|
||||
2. Przenieś wektor światła i wektor widoku do przestrzeni stycznych
|
||||
1. Musimy przekształcić wektor światła (L) i wektor widoku (V) do przestrzeni stycznych. Zrobimy to w vertex shaderze. W tym celu przenieś potrzebne dane dotyczące światła i kamery (uniformy `lightPos` i `cameraPos`) z **fragment shadera** do **vertex shadera.**
|
||||
|
||||
2. Oblicz wektor `viewDir` jako znormalizowana różnice `cameraPos` i `fragPos` (tu jeszcze działamy w przestrzeni świata). Analogicznie oblicz `lightDir` jako różnicę `lightPos` i `fragPos`
|
||||
|
||||
3. Przekształć wektory `viewDir` i `lightDir` do przestrzeni stycznej mnożąc je przez macierz **TBN**. Wynik zapisz w zmiennych`viewDirTS` i `lightDirTS` odpowiednio.
|
||||
|
||||
4. Przekaż `viewDirTS` i `lightDirTS` do fragment shadera. (zadeklaruj je jako zmienne `out`)
|
||||
|
||||
> (Sufiks TS oznacza tangent space. Ważne jest, aby oznaczać (np. dopisując coś do nazwy zmiennej) w jakiej przestrzeni znajdują się używane wektory, tak aby poprawnie wykonywać obliczenia. Trzeba zawsze zwracać uwagę na to, w jakiej przestrzeni działamy.)
|
||||
|
||||
3. Przekształć **fragment shader**, by obsługiwał **tangent space**
|
||||
1. Nie potrzebujemy już we **fragment shaderze** informacji na temat pozycji fragmentu i wektora normalnego geometrii, skasuj wiec zmienne przekazujące te wektory pomiędzy shaderami.
|
||||
2. wektora `lightDir` powinniśmy użyć wektora `lightDirTS` (należy go dodatkowo znormalizować), a jako wektor widoku V powinniśmy użyć wektora `viewDirTS` (również należy go znormalizować). Jako wektora N użyj na razie wektora vec3(0,0,1).
|
||||
|
||||
Efekt finalny powinien wyglądać tak samo, jak przed jakąkolwiek zmianą. Następnym krokiem będzie wykorzystanie map normalnych.
|
||||
|
||||
### Wykorzystaj normalmapy
|
||||
|
||||
1. Chcemy wczytywać normalne z tekstury, w tym celu dodaj we **fragment shaderze** dodatkowy sampler do czytania map normalnych, nazwij go `normalSampler`. Pobierz z niego wektor normalny analogicznie, jak czytamy kolor zwykłej tekstury z samplera `textureSampler` i zapisz go w zmiennej `N`.
|
||||
2. Ponieważ w teksturze wartości są w przedziale $[0,1]$, musimy jeszcze przekształcić je do przedziału $[-1,1]$. W tym celu przemnóż wektor N przez 2 i odejmij 1.
|
||||
Na koniec warto jeszcze znormalizować wektor normalny, aby uniknąć błędów związanych z precyzja lub kompresja tekstury.
|
||||
3. Wczytaj pliki zawierające mapy normalnych w kodzie C++ W tym celu załaduj przy użyciu funkcji `Core::LoadTexture` mapy normalnych dla wszystkich modeli. Maja one taką samą nazwę jak zwykle tekstury, tyle że z suffiksem "_normals".
|
||||
4. Zmodyfikuj na koniec funkcje `drawObjectTexture`. Dodaj do niej nowy argument `GLuint normalmapId`, który będzie służył do przekazywania id tekstury zawierającej mapę normalnych. Przy użyciu funkcji `Core::SetActiveTexture` załaduj `normalmapId` jako `normalSampler` i ustaw jednostkę teksturowania nr 1.
|
||||
Argument odpowiadający za normalne w miejscach wywołania funkcji `drawObjectTexture`.
|
||||
|
||||
|
||||
### Zadanie*
|
||||
Ustaw mapy normalne do statku planety i księżyca (lub przynajmniej 3 obiektów, jeżeli rysujesz swoją scenę). Wykorzystaj multitexturing na statku, musisz w takim wypadku mieszać zarówno tekstury koloru i normalanych.
|
||||
|
||||
## SkyBox
|
||||
Cubemapy są specjalnym rodzajem tekstur. Zawieją one 6 tekstur, każda z niej odpowiada za inną ścianę sześcianu. Nie służy ona do teksturowania zwykłego sześcianu, pozwala ona bowiem próbkować po wektorze kierunku. To znaczy, możemy o tym myśleć jak o kostce, w której środku się znaleźliśmy, co obrazuje poniższy rysunek. W przeciwieństwie do zwykłych tekstur samplujemy ją nie za pomocą dwuwymiarowych współrzędnych UV, ale za pomocą wektora trójwymiarowego, który odpowiada kierunkowi promienia.
|
||||
|
||||
Jednym z zastosowań Cubemapy jest wyświetlanie skyboxa, czyli dalekiego tła dla sceny. Może to być na przykład rozgwieżdżone niebo z górami na horyzoncie albo obraz dalekiej galaktyki.
|
||||
|
||||
### Ładowanie cubemapy
|
||||
Cubemapę generujemy podobnie jak inne tekstury, ale przy bindowaniu należy podać `GL_TEXTURE_CUBE_MAP`.
|
||||
```C++
|
||||
glGenTextures(1, &textureID);
|
||||
glBindTexture(GL_TEXTURE_CUBE_MAP, textureID);
|
||||
```
|
||||
Skoro składa się ona z 6 tekstur, to należy każdą z nich załadować za pomocą `void glTexImage2D( GLenum target, ...)` `taget` wskazuje którą z tekstur ładujemy. Możliwe wartości rozpisane są w tabeli poniżej
|
||||
|Layer number|Texture target | Orientation|
|
||||
|----|--------------------:|-----------:|
|
||||
|0|`GL_TEXTURE_CUBE_MAP_POSITIVE_X` | Right |
|
||||
|1|`GL_TEXTURE_CUBE_MAP_NEGATIVE_X`|Left|
|
||||
|2|`GL_TEXTURE_CUBE_MAP_POSITIVE_Y`|Top|
|
||||
|3|`GL_TEXTURE_CUBE_MAP_NEGATIVE_Y`|Bottom|
|
||||
|4|`GL_TEXTURE_CUBE_MAP_POSITIVE_Z`|Back|
|
||||
|5|`GL_TEXTURE_CUBE_MAP_NEGATIVE_Z`|Front|
|
||||
|
||||
Możemy je ładować w pętli biorąc za kolejne targety `GL_TEXTURE_CUBE_MAP_POSITIVE_X+i`, ale należy pamiętać o powyższej kolejności. Poniższy kod ładuje do wszystkich 6 ścian tę samą teksturę, która znajduje się pod `filepath`.
|
||||
|
||||
```C++
|
||||
|
||||
int w, h;
|
||||
unsigned char *data;
|
||||
for(unsigned int i = 0; i < 6; i++)
|
||||
{
|
||||
unsigned char* image = SOIL_load_image(filepath, &w, &h, 0, SOIL_LOAD_RGBA);
|
||||
glTexImage2D(
|
||||
GL_TEXTURE_CUBE_MAP_POSITIVE_X + i,
|
||||
0, GL_RGBA, w, h, 0, GL_RGBA, GL_UNSIGNED_BYTE, data
|
||||
);
|
||||
}
|
||||
```
|
||||
Na koniec pozostaje ustawić parametry opisujące zachowanie tekstury:
|
||||
```C++
|
||||
glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
|
||||
glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
|
||||
glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
|
||||
glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
|
||||
glTexParameteri(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_WRAP_R, GL_CLAMP_TO_EDGE);
|
||||
```
|
||||
|
||||
### Zadanie
|
||||
Napisz funkcję, która będzie ładować cubmapę bazującą na tablicy 6 stringów i załaduj do niej tekstury z foldera `skybox`.
|
||||
|
||||
### Rysowanie skyboxa
|
||||
Skybox jest sześcianem, wewnątrz którego zamieszamy naszą scenę, przedstawia on dalekie tło, dzięki temu dostajemy iluzję głębi i przestrzeni. Do tego potrzebujemy narysować sześcian i narysować go odpowiednim shaderem. Rysowanie jest bardzo proste, polega wyłącznie na wyświetleniu koloru tekstury. Aby próbkować, teksturę potrzebujemy przesłać pozycję w przestrzeni modelu do shadera fragmentów.
|
||||
|
||||
```C++
|
||||
#version 430 core
|
||||
|
||||
layout(location = 0) in vec3 vertexPosition;
|
||||
|
||||
uniform mat4 transformation;
|
||||
|
||||
out vec3 texCoord;
|
||||
|
||||
void main()
|
||||
{
|
||||
texCoord = vertexPosition;
|
||||
gl_Position = transformation * vec4(vertexPosition, 1.0);
|
||||
}
|
||||
|
||||
```
|
||||
> shader_skybox.vert
|
||||
|
||||
W shaderze fragmentów wystarczy odebrać pozycję i próbkować za jej pomocą teksturę.
|
||||
|
||||
```C++
|
||||
#version 430 core
|
||||
|
||||
uniform samplerCube skybox;
|
||||
|
||||
in vec3 texCoord;
|
||||
|
||||
out vec4 out_color;
|
||||
|
||||
void main()
|
||||
{
|
||||
out_color = texture(skybox,texCoord);
|
||||
}
|
||||
|
||||
```
|
||||
> shader_skybox.frag
|
||||
|
||||
### Zadanie
|
||||
W modelach znajduje się `cube.obj`, załaduj go i narysuj shaderami `shader_skybox.vert` i `shader_skybox.vert`. Pamiętaj o przesłaniu macierzy transformacji i tekstury skyboxa. Aktywujemy ją za pomocą instrukcji:
|
||||
```C++
|
||||
glBindTexture(GL_TEXTURE_CUBE_MAP, cubemapTexture);
|
||||
```
|
||||
|
||||
Skybox potencjalnie zasłania pewne obiekty, które są umieszczone trochę dalej. Wynika to z tego, że renderowanie go nadpisuje bufor głębokości. Dlatego narysuj cubemapę z wyłączonym testem głębokości na samym początku. Następnie włącz test głębokości dla reszty sceny.
|
||||
Dezaktywację wykonasz za pomocą instrukcji `glDisable(GL_DEPTH_TEST);`, natomiast aktywację za pomocą`glEnable(GL_DEPTH_TEST);`.
|
||||
|
||||
Skybox reprezentuje obiekty, które są bardzo daleko. Tę iluzję możemy utracić, gdy kamera przysunie się zbyt blisko do skyboxa. Aby tego uniknąć, musimy tak umieścić skybox, by kamera zawsze była w jego środku. Przesuń skybox do pozycji kamery z użyciem macierzy translacji.

|
||||
<p>Physically based rendering jest zbiorem technik renderowania, które bazują na teorii, która ma za zadanie odwzorowywać świat rzeczywisty.</p>
|
||||
<p>Podstawową dla obliczenia jest <em>rendering equation</em> następującej postaci.</p>
|
||||
<p><span class="math display">\[L_o(p,\omega_o)=\int_\Omega f_r(p,\omega_i,\omega_o)L_i(p,\omega_i)n\cdot \omega_i\ d\omega_i\]</span> Całka przechodzi po wszystkich kierunkach na półkuli <span class="math inline">\(\Omega\)</span> oblicza wyjściowe oświetlenie <span class="math inline">\(L_O\)</span> bazując na wejściowym oświetleniu <span class="math inline">\(L_i\)</span> i funkcji <span class="math inline">\(f_r\)</span> znanej jako <strong>BRDF</strong>, czyli <em>bidirectional reflective distribution function</em>. W najbardziej ogólnym przypadku należałoby traktować <span class="math inline">\(L_i\)</span> jako dystrybucję i jest nadmiernym formalizmem w naszym przypadku, gdy będziemy wykorzystywać wyłącznie światła punktowe i kierunkowe. Dlatego o powyższej całce możemy myśleć jak o sumie po źródłach światła.</p>
|
||||
<p>By uzyskać realistyczny efekt, potrzebujemy realistycznej funkcji <span class="math inline">\(f_r\)</span>. Wybierzemy <em>Cook-Torrance BRDF</em>, który jest najczęściej wykorzystywaną funkcją przy liczeniu PBR w czasie rzeczywistym.</p>
|
||||
<p><em>Cook-Torrance BRDF</em> rozdzielamy na światło rozproszone (diffuse) i odbite kierunkowo (specular)</p>
|
||||
<p><span class="math display">\[f_r=k_d f_{lambert}+k_s f_{cook−torrance},\]</span> gdzie <span class="math inline">\(k_d\)</span> i <span class="math inline">\(k_s\)</span> to są współczynniki, rozdzielające ile światła zostało rozproszone a ile odbite, ich suma musi być równa 1. komponent <span class="math inline">\(f_{lambert}\)</span> jest znany jako <em>Lambertian diffuse</em> i wynosi <span class="math display">\[f_{lambert}=\frac{c}{\pi}\]</span> przy czym <span class="math inline">\(c\)</span> to jest jest kolorem powierzchni a <span class="math inline">\(\pi\)</span> odpowiada za normalizację.</p>
|
||||
<p>Część odbicia kierunkowego jest bardziej skomplikowana i wygląda następująco:</p>
|
||||
<p><span class="math display">\[f_{cook−torrance}=\frac{DFG}{4(w_o\cdot n)(w_i\cdot n)}\]</span> gdzie <span class="math inline">\(D\)</span>, <span class="math inline">\(F\)</span> i <span class="math inline">\(G\)</span> są funkcjami, które zależą od normalnej, wektora wejściowego i wyjściowego oraz parametrów chropowatości <span class="math inline">\(\alpha\)</span> i odbicia <span class="math inline">\(F_0\)</span>. Te funkcje to odpowiednio: - <span class="math inline">\(D\)</span> - <strong>Normal distribution function</strong> przybliża ilość powierzchni, która jest ustawiona prostopadle do wektora połówkowego korzystamy z funkcji Trowbridge-Reitz GGX <span class="math display">\[D(n,h,\alpha) = \frac{\alpha^2}{π((n⋅h)^2(α^2−1)+1)^2},\]</span> gdzie <span class="math inline">\(h\)</span> to: <span class="math display">\[h = \frac{\omega_o+\omega_i}{||\omega_o+\omega_i||}\]</span> - G - <strong>Geometry function</strong> opisuje stopień samo-zacieninienia. Wykorzystujemy Schlick-GGX <span class="math display">\[G(n,\omega_o,k)=\frac{n⋅\omega_o}{(n⋅\omega_o)(1−k)+k}\]</span> przy czym <span class="math inline">\(k\)</span> wynosi <span class="math display">\[k=\frac{(\alpha+1)^2}{8}\]</span> - F - <strong>Fresnel equation</strong> opisuje stopień odbicia w zależności od kąta padania. Wykorzystujemy aproksymację Fresnela-Schlicka <span class="math display">\[F(h,v,F_0)=F_0+(1−F_0)(1−(h⋅v))^5\]</span> Parametr <span class="math inline">\(F_0\)</span> jest własnością materiału dla uproszczenia uznaje się, że niemetale mają wartość (0.04,0.4,0.4) a dla metali jest ona równa kolorowi obiektu. Wprowadza się <strong>parametr metaliczności</strong>, który jest współczynnikiem, jakim miksujemy między (0.04,0.4,0.4) a kolorem, żeby uzyskać <span class="math inline">\(F_0\)</span>.</p>
|
||||
<h3 id="zadanie">Zadanie</h3>
|
||||
<p>W projekcie znajduje się jedna kula, punktowe oświetlenie i cieniowanie Phonga. Zaimplementuj PBR i rozmieść kule w macierzy 10 x 10 zmieniając stopniowo w nich parametr chropowatości <span class="math inline">\(\alpha\)</span> i metaliczności, jak na poniższym obrazku. <img src="./img/lighting_result.png" /></p>
|
||||
<h2 id="teksturowanie">Teksturowanie</h2>
|
||||
<p>Do uzyskania realistycznego efektu wykorzystuje się szereg tekstur:</p>
|
||||
<p><img src="./img/textures.png" /> Tekstury <strong>Albedo</strong> i <strong>Normalnych</strong> odpowiadają za kolor i normalne jak przy cieniowaniu Phonga. <strong>Metalic</strong> i <strong>Roughness</strong> przechowuje wartość metaliczności i chropowatości, które pojawiły się w BRDF. Natomiast <strong>AO</strong> (ambient occlision) odpowiada za stopień samo-zacienienia, który modyfikuje oświetlenie ambientowe w danym punkcie, uwzględnienie jej podkreśla detale obiektów.</p>
|
||||
<p>Karty graficzne posiadają ograniczenia, jeżeli chodzi o ilość tekstur, które można przesłać za jednym razem (współcześnie są to 32 tekstury). Może być to znaczące ograniczenie, dlatego <strong>AO</strong> <strong>Roughness</strong> i <strong>Metalic</strong> mogą być przesłane w jednej teksturze kolejno jako kanał r, g i b. Taką teksturę określa się jako arm od pierwszych liter nazw.</p>
|
||||
<h3 id="zadanie-1">Zadanie</h3>
|
||||
<p>W <code>ex_8_2.hpp</code> znajduje się podstawowa scena. Zaimplementuj w niej PBR z użyciem tekstur. Stwórz nową parę shaderów, które będą obsługiwać PBR<img src="./img/textures.png" />W oparciu o tekstury. Wyświetl statek zestawem tekstur w folderze <code>textures/spaceshipPBR</code>. Możesz też wziąć swój układ słoneczny z poprzednich zajęć. Ładowanie tekstur jest męczące, napisz klasę/strukturę <code>PBRTexturesHandler</code>, która przechowuje zestaw tekstur <em>albedo</em>, <em>normal</em> i <em>arm</em>. Posiada konstruktor, który ładuje tekstury po ścieżkach oraz funkcję <code>activateTextures(int[] indices)</code>, która aktywuje tekstury z indeksami podanymi w tablicy. <code>int[] indices</code>.</p>
|
||||
<h2 id="pbr-multitexturing">PBR Multitexturing</h2>
|
||||
<p>Podobnie jak w przypadku zwykłych tekstur możemy mieszać tekstury przesyłane przez PBR, należy wtedy mieszać wszystkie tekstury z takim samym współczynnikiem. Jednak stopniowe przejście z jednej tekstury do drugiej często prowadzi to do nienaturalnych rezultatów, gdy próbujemy mieszać tekstury o różnej częstotliwości detali, jak na przykład poniżej: <img src="./img/blending1.webp" /> W prawdziwym świecie, przy stopniowej zmianie z kamiennego podłoża na piaszczyste, wiedzielibyśmy, jak piasek stopniowo zaczyna wypełniać szpary między kamieniami i przykrywać je coraz bardziej. Istnieje wiele metod mieszania tekstur np <a href="https://onlinelibrary.wiley.com/doi/10.1002/cav.1460">ta</a>. My wykorzystamy technikę opartą na mapach wysokości, opisaną w <a href="https://www.gamedeveloper.com/programming/advanced-terrain-texture-splatting">https://www.gamedeveloper.com/programming/advanced-terrain-texture-splatting</a>.</p>
|
||||
<blockquote>
|
||||
<p>Mapa wysokości to dodatkowa tekstura, która wskazuje wysokość obiektów znajdujących się na teksturze względem płaskiej powierzchni. Może być również wykorzystana przy paralax mappingu czy tessalacji. Jest ona nazywana po angielsku <em>heightmap</em>, <em>displacement map</em> czy <em>bump map</em> w zależności od zastosowania. Przykładowe znajdują się w teksutrach.</p>
|
||||
</blockquote>
|
||||
<p>Możemy te mapy wykorzystać do mieszania dwóch map tak, że wyświetlana będzie ta, która jest wyżej. Zaprezentować to możemy w poniższym jednowymiarowym schemacie. Niebieska linia reprezentuje mapę piasku a czerwona kamieni. <img src="./img/2.png" /> Jako rezultat otrymujemy <img src="./img/3.webp" /></p>
|
||||
<p>Kod funkcji mieszającej:</p>

<div class="sourceCode" id="cb1"><pre class="sourceCode c++"><code class="sourceCode cpp"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a>float3 blend(float3 texture1, <span class="dt">float</span> height1, float3 texture2, <span class="dt">float</span> height2, <span class="dt">float</span> blend_ratio)</span>

<span id="cb1-9"><a href="#cb1-9" aria-hidden="true" tabindex="-1"></a>}</span></code></pre></div>
|
||||
<p>To pozwala nam zmieszać dwie tekstury. Jednak samo w sobie nie powoduję przejścia z jednej do drugiej, to możemy osiągnąć modyfikując wysokość parametrem <code>blend_ratio</code>, który będzie z zakresu od 0 do 1. Na jednowymiarowym schemacie wartość wysokości wygląda to następująco. <img src="./img/4.png" /> Daje nam to to poniższy efekt <img src="./img/5.webp" /> Kod nowej funkcji mieszającej:</p>

|
||||
<p>To podejście dało nam bardziej naturalne przejście z piasku do kamieni. Widać jak kamienie stopniowo wyłaniają się spod piasku. Jednak pojawiły się artefakty w miejscach, gdzie wartości mapy wysokości są bardzo zbliżone. Wynika to z ograniczeń kwantyzacji. By zminimalizować te błędy, będziemy mieszać wartości tekstur, ale tylko, gdy wartości będą blisko siebie. <img src="./img/6.webp" /> Zdefiniujemy dodatkowy parametr <code>mix_threshold</code>, który będzie określał, jak blisko mają być wartości, żeby je mieszać. Jeżeli różnica między jedną wysokością a drugą będzie mniejsza od <code>mix_threshold</code> to będziemy je mieszać proporcjonalnie do ich różnicy podzielonej przez <code>mix_threshold</code>, w przeciwnym wypadku wybierzemy tą, która jest wyżej. W celu optymalizacji zamiast optymalizacji korzystamy z funkcji clamp</p>

# Physically based rendering
|
||||
|
||||
Physically based rendering jest zbiorem technik renderowania, które bazują na teorii, która ma za zadanie odwzorowywać świat rzeczywisty.
|
||||
|
||||
Podstawową dla obliczenia jest *rendering equation* następującej postaci.
|
||||
|
||||
$$L_o(p,\omega_o)=\int_\Omega f_r(p,\omega_i,\omega_o)L_i(p,\omega_i)n\cdot \omega_i\ d\omega_i$$
|
||||
Całka przechodzi po wszystkich kierunkach na półkuli $\Omega$ oblicza wyjściowe oświetlenie $L_O$ bazując na wejściowym oświetleniu $L_i$ i funkcji $f_r$ znanej jako **BRDF**, czyli *bidirectional reflective distribution function*. W najbardziej ogólnym przypadku należałoby traktować $L_i$ jako dystrybucję i jest nadmiernym formalizmem w naszym przypadku, gdy będziemy wykorzystywać wyłącznie światła punktowe i kierunkowe. Dlatego o powyższej całce możemy myśleć jak o sumie po źródłach światła.
|
||||
|
||||
By uzyskać realistyczny efekt, potrzebujemy realistycznej funkcji $f_r$. Wybierzemy *Cook-Torrance BRDF*, który jest najczęściej wykorzystywaną funkcją przy liczeniu PBR w czasie rzeczywistym.
|
||||
|
||||
*Cook-Torrance BRDF* rozdzielamy na światło rozproszone (diffuse) i odbite kierunkowo (specular)
|
||||
|
||||
$$f_r=k_d f_{lambert}+k_s f_{cook−torrance},$$
|
||||
gdzie $k_d$ i $k_s$ to są współczynniki, rozdzielające ile światła zostało rozproszone a ile odbite, ich suma musi być równa 1. komponent $f_{lambert}$ jest znany jako *Lambertian diffuse* i wynosi
|
||||
$$f_{lambert}=\frac{c}{\pi}$$
|
||||
przy czym $c$ to jest jest kolorem powierzchni a $\pi$ odpowiada za normalizację.
|
||||
|
||||
Część odbicia kierunkowego jest bardziej skomplikowana i wygląda następująco:
|
||||
|
||||
$$f_{cook−torrance}=\frac{DFG}{4(w_o\cdot n)(w_i\cdot n)}$$
|
||||
gdzie $D$, $F$ i $G$ są funkcjami, które zależą od normalnej, wektora wejściowego i wyjściowego oraz parametrów chropowatości $\alpha$ i odbicia $F_0$. Te funkcje to odpowiednio:
|
||||
- $D$ - **Normal distribution function** przybliża ilość powierzchni, która jest ustawiona prostopadle do wektora połówkowego korzystamy z funkcji Trowbridge-Reitz GGX $$D(n,h,\alpha) = \frac{\alpha^2}{π((n⋅h)^2(α^2−1)+1)^2},$$
|
||||
gdzie $h$ to: $$h = \frac{\omega_o+\omega_i}{||\omega_o+\omega_i||}$$
|
||||
- G - **Geometry function** opisuje stopień samo-zacieninienia. Wykorzystujemy Schlick-GGX
|
||||
$$G(n,\omega_o,k)=\frac{n⋅\omega_o}{(n⋅\omega_o)(1−k)+k}$$
|
||||
przy czym $k$ wynosi
|
||||
$$k=\frac{(\alpha+1)^2}{8}$$
|
||||
- F - **Fresnel equation** opisuje stopień odbicia w zależności od kąta padania. Wykorzystujemy aproksymację Fresnela-Schlicka
|
||||
$$F(h,v,F_0)=F_0+(1−F_0)(1−(h⋅v))^5$$
|
||||
Parametr $F_0$ jest własnością materiału dla uproszczenia uznaje się, że niemetale mają wartość (0.04,0.4,0.4) a dla metali jest ona równa kolorowi obiektu. Wprowadza się **parametr metaliczności**, który jest współczynnikiem, jakim miksujemy między (0.04,0.4,0.4) a kolorem, żeby uzyskać $F_0$.
|
||||
|
||||
### Zadanie
|
||||
W projekcie znajduje się jedna kula, punktowe oświetlenie i cieniowanie Phonga. Zaimplementuj PBR i rozmieść kule w macierzy 10 x 10 zmieniając stopniowo w nich parametr chropowatości $\alpha$ i metaliczności, jak na poniższym obrazku.
|
||||
|
||||
|
||||
## Teksturowanie
|
||||
Do uzyskania realistycznego efektu wykorzystuje się szereg tekstur:
|
||||
|
||||
|
||||
Tekstury **Albedo** i **Normalnych** odpowiadają za kolor i normalne jak przy cieniowaniu Phonga. **Metalic** i **Roughness** przechowuje wartość metaliczności i chropowatości, które pojawiły się w BRDF. Natomiast **AO** (ambient occlision) odpowiada za stopień samo-zacienienia, który modyfikuje oświetlenie ambientowe w danym punkcie, uwzględnienie jej podkreśla detale obiektów.
|
||||

Karty graficzne posiadają ograniczenia, jeżeli chodzi o ilość tekstur, które można przesłać za jednym razem (współcześnie są to 32 tekstury). Może być to znaczące ograniczenie, dlatego **AO** **Roughness** i **Metalic** mogą być przesłane w jednej teksturze kolejno jako kanał r, g i b. Taką teksturę określa się jako arm od pierwszych liter nazw.
|
||||
|
||||
### Zadanie
|
||||
W `ex_8_2.hpp` znajduje się podstawowa scena. Zaimplementuj w niej PBR z użyciem tekstur.
|
||||
Stwórz nową parę shaderów, które będą obsługiwać PBRW oparciu o tekstury. Wyświetl statek zestawem tekstur w folderze `textures/spaceshipPBR`. Możesz też wziąć swój układ słoneczny z poprzednich zajęć.
|
||||
Ładowanie tekstur jest męczące, napisz klasę/strukturę `PBRTexturesHandler`, która przechowuje zestaw tekstur *albedo*, *normal* i *arm*. Posiada konstruktor, który ładuje tekstury po ścieżkach oraz funkcję `activateTextures(int[] indices)`, która aktywuje tekstury z indeksami podanymi w tablicy. `int[] indices`.
|
||||
|
||||
## PBR Multitexturing
|
||||
Podobnie jak w przypadku zwykłych tekstur możemy mieszać tekstury przesyłane przez PBR, należy wtedy mieszać wszystkie tekstury z takim samym współczynnikiem. Jednak stopniowe przejście z jednej tekstury do drugiej często prowadzi to do nienaturalnych rezultatów, gdy próbujemy mieszać tekstury o różnej częstotliwości detali, jak na przykład poniżej:
|
||||
|
||||
W prawdziwym świecie, przy stopniowej zmianie z kamiennego podłoża na piaszczyste, wiedzielibyśmy, jak piasek stopniowo zaczyna wypełniać szpary między kamieniami i przykrywać je coraz bardziej.
|
||||
Istnieje wiele metod mieszania tekstur np [ta](https://onlinelibrary.wiley.com/doi/10.1002/cav.1460). My wykorzystamy technikę opartą na mapach wysokości, opisaną w
|
||||
[https://www.gamedeveloper.com/programming/advanced-terrain-texture-splatting](https://www.gamedeveloper.com/programming/advanced-terrain-texture-splatting).
|
||||
|
||||
> Mapa wysokości to dodatkowa tekstura, która wskazuje wysokość obiektów znajdujących się na teksturze względem płaskiej powierzchni. Może być również wykorzystana przy paralax mappingu czy tessalacji. Jest ona nazywana po angielsku *heightmap*, *displacement map* czy *bump map* w zależności od zastosowania. Przykładowe znajdują się w teksutrach.
|
||||
|
||||
Możemy te mapy wykorzystać do mieszania dwóch map tak, że wyświetlana będzie ta, która jest wyżej. Zaprezentować to możemy w poniższym jednowymiarowym schemacie. Niebieska linia reprezentuje mapę piasku a czerwona kamieni.
|
||||
|
||||
Jako rezultat otrymujemy
|
||||
|
||||
|
||||
Kod funkcji mieszającej:
|
||||
```C++
|
||||
float3 blend(float3 texture1, float height1, float3 texture2, float height2, float blend_ratio)
|
||||
{
|
||||
if (height1>height2){
|
||||
return texture1;
|
||||
}
|
||||
else{
|
||||
return texture2;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
To pozwala nam zmieszać dwie tekstury. Jednak samo w sobie nie powoduję przejścia z jednej do drugiej, to możemy osiągnąć modyfikując wysokość parametrem `blend_ratio`, który będzie z zakresu od 0 do 1. Na jednowymiarowym schemacie wartość wysokości wygląda to następująco.
|
||||
|
||||
Daje nam to to poniższy efekt
|
||||
|
||||
Kod nowej funkcji mieszającej:
|
||||
```C++
|
||||
float3 blend(float3 texture1, float height1, float3 texture2, float height2, float blend_ratio)
|
||||
{
|
||||
float h1=height1+1.0-blend_ratio;
|
||||
float h2=height2+blend_ratio;
|
||||
if (h1>h2){
|
||||
return texture1;
|
||||
}
|
||||
else{
|
||||
return texture2;
|
||||
}
|
||||
}
|
||||
```
|
||||
To podejście dało nam bardziej naturalne przejście z piasku do kamieni. Widać jak kamienie stopniowo wyłaniają się spod piasku. Jednak pojawiły się artefakty w miejscach, gdzie wartości mapy wysokości są bardzo zbliżone. Wynika to z ograniczeń kwantyzacji. By zminimalizować te błędy, będziemy mieszać wartości tekstur, ale tylko, gdy wartości będą blisko siebie.
|
||||
|
||||
Zdefiniujemy dodatkowy parametr `mix_threshold`, który będzie określał, jak blisko mają być wartości, żeby je mieszać. Jeżeli różnica między jedną wysokością a drugą będzie mniejsza od `mix_threshold` to będziemy je mieszać proporcjonalnie do ich różnicy podzielonej przez `mix_threshold`, w przeciwnym wypadku wybierzemy tą, która jest wyżej. W celu optymalizacji zamiast optymalizacji korzystamy z funkcji clamp
|
||||
|
||||
```C++
|
||||
float3 blend(float3 texture1, float height1, float3 texture2, float height2, float blend_ratio)
|
||||
{
|
||||
float mix_threshold=0.1;
|
||||
float h1=height1+1.0-blend_ratio;
|
||||
float h2=height2+blend_ratio;
|
||||
float havg=(h1+h2)/2.;
|
||||
|
||||
h1 = clamp((h1-hav+0.5*mix_threshold)/(mix_threshold),0.,1.);
|
||||
h2 = clamp((h2-hav+0.5*mix_threshold)/(mix_threshold),0.,1.);
|
||||
|
||||
return (texture1*h1+texture2*h2)
|
||||
}
|
||||
```
|
||||
|
||||
Stosunek w jakim je zmieszamy:
|
||||
|
||||
|
||||
Finalna tekstura
|
||||
|
||||
|
||||
### Zadanie
|
||||
W teksturach znajduje plik `heightmap.png` wykorzystaj go jako mapę wysokości przy rysowaniu jednej z planet. Mapa ta zawiera wartości, od 0 do 1. Dla różnych wysokości chcemy wykorzystywać różne tekstury, ustal na przykład, że poniżej 0,3 znajduje się woda, między 0,3 a 0,6 trawa, natomiast powyżej skały.
|
||||
|
||||
### Zadanie*
|
||||
Zmodyfikuj swój układ słoneczny z poprzednich zajęć, zmień w nim model oświetlenia z Phonga na PBR. Tekstury możesz pobrać na przykład z [https://polyhaven.com/textures](https://polyhaven.com/textures)
|
||||
lub [www.texturecan.com](www.texturecan.com).

An ideal submission includes a small piece of code that anyone can paste into one of the examples applications (examples/*/main.cpp) or the demo (imgui_demo.cpp) to understand and reproduce it. Narrowing your problem to its shortest and purest form is the easiest way to understand it, explain it and fix it. Please test your shortened code to ensure it exhibits the problem. Often while creating the MCVE you will solve the problem! Many questions that are missing a standalone verifiable example are missing the actual cause of their issue in the description, which ends up wasting everyone's time."

// dear imgui: Renderer + Platform Backend for Allegro 5
|
||||
// (Info: Allegro 5 is a cross-platform general purpose library for handling windows, inputs, graphics, etc.)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy ALLEGRO_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
||||
// [X] Platform: Clipboard support (from Allegro 5.1.12)
|
||||
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
|
||||
// Issues:
|
||||
// [ ] Renderer: The renderer is suboptimal as we need to convert vertices manually.
|
||||
// [ ] Platform: Missing gamepad support.
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
||||
// Learn about Dear ImGui:
|
||||
// - FAQ https://dearimgui.com/faq
|
||||
// - Getting Started https://dearimgui.com/getting-started
|
||||
// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
|
||||
// - Introduction, links and more at the top of imgui.cpp
|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-11-30: Renderer: Restoring using al_draw_indexed_prim() when Allegro version is >= 5.2.5.
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|
||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
||||
// 2022-01-17: Inputs: always calling io.AddKeyModsEvent() next and before key event (not in NewFrame) to fix input queue with very low framerates.
|
||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
||||
// 2021-12-08: Renderer: Fixed mishandling of the the ImDrawCmd::IdxOffset field! This is an old bug but it never had an effect until some internal rendering changes in 1.86.
|
||||
// 2021-08-17: Calling io.AddFocusEvent() on ALLEGRO_EVENT_DISPLAY_SWITCH_OUT/ALLEGRO_EVENT_DISPLAY_SWITCH_IN events.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-05-19: Renderer: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-02-18: Change blending equation to preserve alpha in output buffer.
|
||||
// 2020-08-10: Inputs: Fixed horizontal mouse wheel direction.
|
||||
// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
|
||||
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
|
||||
// 2019-05-11: Inputs: Don't filter character value from ALLEGRO_EVENT_KEY_CHAR before calling AddInputCharacter().
|
||||
// 2019-04-30: Renderer: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2018-11-30: Platform: Added touchscreen support.
|
||||
// 2018-11-30: Misc: Setting up io.BackendPlatformName/io.BackendRendererName so they can be displayed in the About Window.
|
||||
// 2018-06-13: Platform: Added clipboard support (from Allegro 5.1.12).
|
||||
// 2018-06-13: Renderer: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-06-13: Renderer: Stopped using al_draw_indexed_prim() as it is buggy in Allegro's DX9 backend.
|
||||
// 2018-06-13: Renderer: Backup/restore transform and clipping rectangle.
|
||||
// 2018-06-11: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
|
||||
// 2018-04-18: Misc: Renamed file from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp.
|
||||
// 2018-04-18: Misc: Added support for 32-bit vertex indices to avoid conversion at runtime. Added imconfig_allegro5.h to enforce 32-bit indices when included from imgui.h.
|
||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplAllegro5_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.

// Implemented features:
|

// [X] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy ALLEGRO_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|

// [X] Platform: Clipboard support (from Allegro 5.1.12)
|
||||
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
|
||||
// Issues:
|
||||
// [ ] Renderer: The renderer is suboptimal as we need to unindex our buffers and convert vertices manually.
|
||||
// [ ] Platform: Missing gamepad support.
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.

// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy AKEYCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]

// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen.
|

// Missing features:
|

// [ ] Platform: Clipboard support.
|
||||
// [ ] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|

// [ ] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'. FIXME: Check if this is even possible with Android.
|
||||
// Important:
|
||||
// - Consider using SDL or GLFW backend on Android, which will be more full-featured than this.
|
||||
// - FIXME: On-screen keyboard currently needs to be enabled by the application (see examples/ and issue #3446)

// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-05-19: DirectX10: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-02-18: DirectX10: Change blending equation to preserve alpha in output buffer.
|
||||
// 2019-07-21: DirectX10: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData().
|
||||
// 2019-05-29: DirectX10: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX10: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-07-13: DirectX10: Fixed unreleased resources in Init and Shutdown functions.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_dx10.cpp/.h away from the old combined DX10+Win32 example.
|
||||
// 2018-06-08: DirectX10: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-04-09: Misc: Fixed erroneous call to io.Fonts->ClearInputData() + ClearTexData() that was left in DX10 example but removed in 1.47 (Nov 2015) on other backends.
|
||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX10_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2016-05-07: DirectX10: Disabling depth-write.

// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-05-19: DirectX11: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.
|
||||
// 2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).
|
||||
// 2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.
|
||||
// 2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
|
||||
// 2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.
|
||||
// 2018-06-08: DirectX11: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2016-05-07: DirectX11: Disabling depth-write.

|

|

// - [Solution 3] IDE/msbuild: edit imconfig.h and add '#define ImTextureID ImU64' (prefer solution 2 to create your own config file!)

|

|

// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'D3D12_GPU_DESCRIPTOR_HANDLE' as ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
|

// Important: to compile on 32-bit systems, this backend requires code to be compiled with '#define ImTextureID ImU64'.

|

// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.

// dear imgui: Renderer Backend for DirectX9
|
||||
// This needs to be used along with a Platform Backend (e.g. Win32)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'LPDIRECT3DTEXTURE9' as ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
||||
// Learn about Dear ImGui:
|
||||
// - FAQ https://dearimgui.com/faq
|
||||
// - Getting Started https://dearimgui.com/getting-started
|
||||
// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
|
||||
// - Introduction, links and more at the top of imgui.cpp
|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-06-25: DirectX9: Explicitly disable texture state stages after >= 1.
|
||||
// 2021-05-19: DirectX9: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-04-23: DirectX9: Explicitly setting up more graphics states to increase compatibility with unusual non-default states.
|
||||
// 2021-03-18: DirectX9: Calling IDirect3DStateBlock9::Capture() after CreateStateBlock() as a workaround for state restoring issues (see #3857).
|
||||
// 2021-03-03: DirectX9: Added support for IMGUI_USE_BGRA_PACKED_COLOR in user's imconfig file.
|
||||
// 2021-02-18: DirectX9: Change blending equation to preserve alpha in output buffer.
|
||||
// 2019-05-29: DirectX9: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX9: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2019-03-29: Misc: Fixed erroneous assert in ImGui_ImplDX9_InvalidateDeviceObjects().
|
||||
// 2019-01-16: Misc: Disabled fog before drawing UI's. Fixes issue #2288.
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_dx9.cpp/.h away from the old combined DX9+Win32 example.
|
||||
// 2018-06-08: DirectX9: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-05-07: Render: Saving/restoring Transform because they don't seem to be included in the StateBlock. Setting shading mode to Gouraud.
|
||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX9_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.

// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2023-12-19: Emscripten: Added ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback() to register canvas selector and auto-resize GLFW window.
|
||||
// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys.
|
||||
// 2023-07-18: Inputs: Revert ignoring mouse data on GLFW_CURSOR_DISABLED as it can be used differently. User may set ImGuiConfigFLags_NoMouse if desired. (#5625, #6609)
|
||||
// 2023-06-12: Accept glfwGetTime() not returning a monotonically increasing value. This seems to happens on some Windows setup when peripherals disconnect, and is likely to also happen on browser + Emscripten. (#6491)
|
||||
// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen/ImGuiMouseSource_Pen on Windows ONLY, using a custom WndProc hook. (#2702)
|
||||
// 2023-03-16: Inputs: Fixed key modifiers handling on secondary viewports (docking branch). Broken on 2023/01/04. (#6248, #6034)
|
||||
// 2023-03-14: Emscripten: Avoid using glfwGetError() and glfwGetGamepadState() which are not correctly implemented in Emscripten emulation. (#6240)
|
||||
// 2023-02-03: Emscripten: Registering custom low-level mouse wheel handler to get more accurate scrolling impulses on Emscripten. (#4019, #6096)
|
||||
// 2023-01-04: Inputs: Fixed mods state on Linux when using Alt-GR text input (e.g. German keyboard layout), could lead to broken text input. Revert a 2022/01/17 change were we resumed using mods provided by GLFW, turns out they were faulty.
|
||||
// 2022-11-22: Perform a dummy glfwGetError() read to cancel missing names with glfwGetKeyName(). (#5908)
|
||||
// 2022-10-18: Perform a dummy glfwGetError() read to cancel missing mouse cursors errors. Using GLFW_VERSION_COMBINED directly. (#5785)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|
||||
// 2022-09-01: Inputs: Honor GLFW_CURSOR_DISABLED by not setting mouse position *EDIT* Reverted 2023-07-18.
|
||||
// 2022-04-30: Inputs: Fixed ImGui_ImplGlfw_TranslateUntranslatedKey() for lower case letters on OSX.
|
||||
// 2022-03-23: Inputs: Fixed a regression in 1.87 which resulted in keyboard modifiers events being reported incorrectly on Linux/X11.
|
||||
// 2022-02-07: Added ImGui_ImplGlfw_InstallCallbacks()/ImGui_ImplGlfw_RestoreCallbacks() helpers to facilitate user installing callbacks after initializing backend.
|
||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
||||
// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
|
||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
||||
// 2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
|
||||
// 2022-01-12: *BREAKING CHANGE*: Now using glfwSetCursorPosCallback(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetCursorPosCallback() and forward it to the backend via ImGui_ImplGlfw_CursorPosCallback().
|
||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
||||
// 2022-01-05: Inputs: Converting GLFW untranslated keycodes back to translated keycodes (in the ImGui_ImplGlfw_KeyCallback() function) in order to match the behavior of every other backend, and facilitate the use of GLFW with lettered-shortcuts API.
|
||||
// 2021-08-17: *BREAKING CHANGE*: Now using glfwSetWindowFocusCallback() to calling io.AddFocusEvent(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() and forward it to the backend via ImGui_ImplGlfw_WindowFocusCallback().
|
||||
// 2021-07-29: *BREAKING CHANGE*: Now using glfwSetCursorEnterCallback(). MousePos is correctly reported when the host platform window is hovered but not focused. If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() callback and forward it to the backend via ImGui_ImplGlfw_CursorEnterCallback().
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
|
||||
// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
|
||||
// 2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
|
||||
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
|
||||
// 2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
|
||||
// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
|
||||
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
|
||||
// 2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
|
||||
// 2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
|
||||
// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_glfw.cpp/.h away from the old combined GLFW+OpenGL/Vulkan examples.
|
||||
// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
|
||||
// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value, passed to glfwSetCursor()).
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
|
||||
// 2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
|
||||
// 2018-01-25: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
|
||||
// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
|
||||
// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
|
||||
// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
|
||||
// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

// [X] Platform: Clipboard support.
|

// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
|

// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLFW_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]

// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|

// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
