PxParticleSystemCallback

Defined in include/PxParticleSystem.h

class PxParticleSystemCallback

Particle system callback base class to schedule work that should be done before, while or after the particle system updates.

A call to fetchResultsParticleSystem() on the PxScene will synchronize the work such that the caller knows that all tasks of this callback completed.

Public Functions

virtual void onBegin(const PxGpuMirroredPointer<PxGpuParticleSystem> &gpuParticleSystem, CUstream stream) = 0

Method gets called when dirty data from the particle system is uploated to the gpu.

Parameters
  • gpuParticleSystem[in] Pointers to the particle systems gpu data available as host accessible pointer and as gpu accessible pointer

  • stream[in] The stream on which all cuda kernel calls get scheduled for execution. A call to fetchResultsParticleSystem() on the PxScene will synchronize the work such that the caller knows that the task completed.

virtual void onAdvance(const PxGpuMirroredPointer<PxGpuParticleSystem> &gpuParticleSystem, CUstream stream) = 0

Method gets called when the simulation step of the particle system is performed.

Parameters
  • gpuParticleSystem[in] Pointers to the particle systems gpu data available as host accessible pointer and as gpu accessible pointer

  • stream[in] The stream on which all cuda kernel calls get scheduled for execution. A call to fetchResultsParticleSystem() on the PxScene will synchronize the work such that the caller knows that the task completed.

virtual void onPostSolve(const PxGpuMirroredPointer<PxGpuParticleSystem> &gpuParticleSystem, CUstream stream) = 0

Method gets called after the particle system simulation step completed.

Parameters
  • gpuParticleSystem[in] Pointers to the particle systems gpu data available as host accessible pointer and as gpu accessible pointer

  • stream[in] The stream on which all cuda kernel calls get scheduled for execution. A call to fetchResultsParticleSystem() on the PxScene will synchronize the work such that the caller knows that the task completed.
