| virtual bool physx::apex::NxClothingPhysicalMesh::getBoneIndices | ( | physx::PxU16 * | boneIndices, |
| physx::PxU32 | byteStride | ||
| ) | const [pure virtual] |
Writes the bone indices into a user specified buffer.
Returns false if the buffer doesn't exist. The buffer must be bigger than sizeof(physx::PxU16) * getNumVertices() * getNumBonesPerVertex(). (numBonesPerVertex is the same as in the graphical mesh for LOD 0)
The bytestride is applied only after writing numBonesPerVertex and thus must be >= sizoef(physx::PxU16) * numBonesPerVertex
| virtual bool physx::apex::NxClothingPhysicalMesh::getBoneWeights | ( | physx::PxF32 * | boneWeights, |
| physx::PxU32 | byteStride | ||
| ) | const [pure virtual] |
Writes the bone weights into a user specified buffer.
Returns false if the buffer doesn't exist. The buffer must be bigger than sizeof(physx::PxF32) * getNumVertices() * getNumBonesPerVertex(). (numBonesPerVertex is the same as in the graphical mesh for LOD 0) The bytestride is applied only after writing numBonesPerVertex and thus must be >= sizoef(physx::PxF32) * numBonesPerVertex
| virtual bool physx::apex::NxClothingPhysicalMesh::getConstrainCoefficients | ( | NxClothingConstrainCoefficients * | coeffs, |
| physx::PxU32 | byteStride | ||
| ) | const [pure virtual] |
Writes the cloth constrain coefficients into a user specified buffer.
Returns false if the buffer doesn't exist. The buffer must be bigger than sizeof(ClothingConstrainCoefficients) * getNumVertices().

| [in] | byteStride | stride of the destination buffer |
| [in] | numIndices | number of indices the buffer can hold. This can be smaller than getNumIndices() |
| virtual bool physx::apex::NxClothingPhysicalMesh::getIndices | ( | physx::PxU32 * | indices, |

| ) | [pure virtual] |
Create a physical mesh from scratch.
Overwrites all vertices/indices, and invalidates all misc vertex buffers. vertices must be physx::PxVec3 and indices physx::PxU32.
| virtual void physx::apex::NxClothingPhysicalMesh::simplify | ( | physx::PxU32 | subdivisions, |

| ) | [pure virtual] |
This will simplify the current mesh.
| [in] | subdivisions | used to derive the maximal length a new edge can get. Divide the bounding box diagonal by this value to get the maximal edge length for newly created edges Use 0 to not restrict the maximal edge length |
| [in] | maxSteps | The maximum number of edges to be considered for simplification. Use 0 to turn off |
| [in] | maxError | The maximal quadric error an edge can cause to be considered simplifyable. Use any value < 0 to turn off |
| [in] | progress | Callback class that will be fired every now and then to update a progress bar in the gui. |
