virtual void addVolume(const PxParticleVolume &volume, const PxParticleVolumeMesh &volumeMesh, const PxU32 *triangles, const PxU32 numTriangles) = 0

Parameters

volume – [in] The PxParticleVolume to be added.
volumeMesh – [in] A PxParticleVolumeMesh that describes the volumes to be added. startIndex is the index into the triangle list of the PxParticleVolumeBufferHelper instance.
triangles – [in] A pointer to the triangle indices of the PxParticleVolume to be added.
numTriangles – [in] The number of triangles of the PxParticleVolume to be added.

virtual void addVolume(const PxU32 particleOffset, const PxU32 numParticles, const PxU32 *triangles, const PxU32 numTriangles) = 0

Adds a volume.

Parameters

particleOffset – [in] The index of the first particle of the cloth that maps to this volume in the PxParticleClothBufferHelper instance.
numParticles – [in] The number of particles of the cloth that maps to this volume in the PxParticleClothBufferHelper instance.
triangles – [in] A pointer to the triangle indices of this volume.
numTriangles – [in] The number of triangles in this volume.
