PxGpuParticleSystem
Defined in include/PxParticleGpu.h
-
class PxGpuParticleSystem
Container class for a GPU particle system.
Used to communicate particle system parameters and simulation state between the internal SDK simulation and the particle system callbacks.
See PxPBDParticleSystem, PxParticleSystemCallback.
