PxMultiCallback#

Defined in include/PxPBDParticleSystem.h

class PxMultiCallback : public PxParticleSystemCallback#

Special callback that forwards calls to arbitrarily many sub-callbacks.

Public Functions

inline PxMultiCallback()#
inline virtual void onPostSolve(
const PxGpuMirroredPointer<PxGpuParticleSystem> &gpuParticleSystem,
CUstream stream,
) override#

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.

inline virtual void onBegin(
const PxGpuMirroredPointer<PxGpuParticleSystem> &gpuParticleSystem,
CUstream stream,
) override#

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.

inline virtual void onAdvance(
const PxGpuMirroredPointer<PxGpuParticleSystem> &gpuParticleSystem,
CUstream stream,
) override#

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.

inline bool addCallback(PxParticleSystemCallback *callback)#

Adds a callback.

Parameters:

callback – [in] The callback to add

Returns:

True if the callback was added

inline bool removeCallback(const PxParticleSystemCallback *callback)#

Removes a callback.

Parameters:

callback – [in] The callback to remove

Returns:

True if the callback was removed
