\brief Helper function to create a fixed joint, using either a PxD6Joint or PxFixedJoint.
|

For fixed joints it is important that the joint frames have the same orientation. This helper function uses an identity rotation for both.
|
||
|
|
It is also important that the joint frames have an equivalent position in world space. The function does not check this, so it is up to users
|
||
|
|
to ensure that this is the case.

This function supports a cone limit shape, defined by two pairs of angular limit values. This can be used to create an asymmetric cone. If the

angular limit values are symmetric (i.e. minLimit1=-maxLimit1 and minLimit2=-maxLimit2) then the cone axis is the X axis in actor0's space.

If the limits are not symmetric, the function rotates the cone axis accordingly so that limits remain symmetric for PhysX. If this happens,

|
the initial joint frames will be different for both actors. By default minLimit1/maxLimit1 are limits around the joint's Y axis, and

minLimit2/maxLimit2 are limits around the joint's Z axis.
