PxIsosurfaceCallback#

class PxIsosurfaceCallback : public PxParticleSystemCallback #

Default implementation of a particle system callback to trigger the isosurface extraction.

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( PxIsosurfaceExtractor *isosurfaceExtractor, PxU32 validPhaseMask = PxParticlePhaseFlag::eParticlePhaseFluid, )#

Initializes the isosurface callback.

Parameters:

isosurfaceExtractor – [in] The isosurface extractor
validPhaseMask – [in] The valid phase mask marking the phase bits that particles must have set in order to contribute to the isosurface

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.
