rotate vector by quaternion (q, w)

helper that creates a plinth whose center matches the particle bounds

* Combines geometry type and static/dynamic flags */

generates a transform matrix with v as the z axis, taken from PBRT

convert an OpenGL style projection matrix to D3D (clip z range [0, 1])

2d gradient function.

performs Atomic operation treating the uav as float (fp32) values the passed sub-opcode 'op' should be an immediate constant byteAddress must be multi
