- Parameters
filters – [in] A device buffer containing PxParticleRigidFilterPair s.
nbFilters – [in] The number of particle-rigid body collision filtering pairs.
-
virtual void setRigidAttachments(PxParticleRigidAttachment *attachments, PxU32 nbAttachments) = 0
Set the particle-rigid body attachments for particles in this particle buffer.
