- Parameters
particleCloth – [in] The PxParticleCloth to be added.
triangles – [in] A pointer to the triangles
numTriangles – [in] The number of triangles
springs – [in] A pointer to the springs
numSprings – [in] The number of springs
restPositions – [in] A pointer to the particle rest positions
numParticles – [in] The number of particles in this cloth

virtual void addCloth(const PxReal blendScale, const PxReal restVolume, const PxReal pressure, const PxU32 *triangles, const PxU32 numTriangles, const PxParticleSpring *springs, const PxU32 numSprings, const PxVec4 *restPositions, const PxU32 numParticles) = 0
Adds a cloth to this PxParticleClothBufferHelper instance.
Adds a cloth to this PxParticleClothBufferHelper instance. With this method the relevant parameters for inflatable simulation (restVolume, pressure) can be set directly.
See also
- Parameters
blendScale – [in] This should be 1.f / (numPartitions + 1) if the springs are partitioned by the user. Otherwise this will be set during spring partitioning.
restVolume – [in] The rest volume of the inflatable
pressure – [in] The pressure of the inflatable. The target inflatable volume is defined as restVolume * pressure. Setting this to > 0.0 will enable inflatable simulation.
triangles – [in] A pointer to the triangles
numTriangles – [in] The number of triangles
springs – [in] A pointer to the springs
numSprings – [in] The number of springs
restPositions – [in] A pointer to the particle rest positions
numParticles – [in] The number of particles in this cloth
-
virtual PxParticleClothDesc &getParticleClothDesc() = 0
Returns a PxParticleClothDesc for this PxParticleClothBufferHelper instance to be used for spring partitioning.
