PxSmoothedPositionCallback#

class PxSmoothedPositionCallback : public PxParticleSystemCallback #

Default implementation of a particle system callback to trigger smoothed position calculations.

A call to fetchResultsParticleSystem() on the PxScene will synchronize the work such that the caller knows that the post solve task completed.

Public Functions

inline void initialize( PxSmoothedPositionGenerator *smoothedPositionGenerator, )#

Initializes the smoothing callback.

Parameters:: smoothedPositionGenerator – [in] The smoothed position generator

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

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>&, CUstream, )#

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>&, CUstream, )#

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.
