// ZADANIE: Powyżej w tablicy points znajdują się wierzchołki 7-kąta foremnego, zadanie polega na narysowaniu gwiazdy siedmioramiennej jak na obrazku zad1b.jpg. Do shadera należy przesłać pozycje wierzchołków i ich odcienie z tablicy hues podobnie jak w zadaniu 1a.
|
|||
|
|
// Idealnie rozwiązane zadanie wymaga użycia indeksowania z użyciem Element Buffer Objects oraz trybu rysowania GL_LINE_STRIP
|
|||
|
|
// (dodatkowe) Jedna krawędź przechodzi przez wszystkie odcienie zamiast z czerwonego do magenty. Co to powoduje? W jaki sposób byś to naprawił?
