virtual void addVolume(

const PxParticleVolume &volume,

const PxParticleVolumeMesh &volumeMesh,

const PxU32 *triangles,

const PxU32 numTriangles,

) = 0

Adds a PxParticleVolume with a PxParticleVolumeMesh.

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.
