addCloth

public void addCloth(PxParticleCloth particleCloth,
 PxU32Ptr triangles,
 int numTriangles,
 PxParticleSpring springs,
 int numSprings,
 PxVec4 restPositions,
 int numParticles)

Adds a PxParticleCloth to this PxParticleClothBufferHelper instance.

Parameters:

particleCloth - The PxParticleCloth to be added.

triangles - A pointer to the triangles

numTriangles - The number of triangles

springs - A pointer to the springs

numSprings - The number of springs

restPositions - A pointer to the particle rest positions

numParticles - The number of particles in this cloth

• PxParticleCloth
• PxParticleSpring

addCloth

public void addCloth(float blendScale,
 float restVolume,
 float pressure,
 PxU32Ptr triangles,
 int numTriangles,
 PxParticleSpring springs,
 int numSprings,
 PxVec4 restPositions,
 int numParticles)

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.

Parameters:

blendScale - This should be 1.f / (numPartitions + 1) if the springs are partitioned by the user. Otherwise this will be set during spring partitioning.

restVolume - The rest volume of the inflatable

pressure - The pressure of the inflatable. The target inflatable volume is defined as restVolume * pressure. Setting this to > 0.0 will enable inflatable simulation.

triangles - A pointer to the triangles

numTriangles - The number of triangles

springs - A pointer to the springs

numSprings - The number of springs

restPositions - A pointer to the particle rest positions

numParticles - The number of particles in this cloth

getParticleClothDesc

public PxParticleClothDesc getParticleClothDesc()

Returns a PxParticleClothDesc for this PxParticleClothBufferHelper instance to be used for spring partitioning.

Returns:

the PxParticleClothDesc.
