Function Documentation

USDSKELIMAGING_API bool UsdSkelImagingComputeBoneJointIndices ( const UsdSkelTopology topology,
VtIntArray *  jointIndices,
size_t  numPoints 
)

Compute joint indices corresponding to each point in a bone mesh. This can be used to animate a bone mesh using normal skinning algos. This does not compute joint weights (they would all be 1s). The numPoints corresponds to the number of points computed by UsdSkelImagingComputeBoneTopology.

USDSKELIMAGING_API bool UsdSkelImagingComputeBoneJointIndices ( const UsdSkelTopology topology,
int jointIndices,
size_t  numPoints 
)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

USDSKELIMAGING_API bool UsdSkelImagingComputeBonePoints ( const UsdSkelTopology topology,
const VtMatrix4dArray &  jointSkelXforms,
size_t  numPoints,
VtVec3fArray *  points 
)

Compute mesh points for imaging a skeleton, given the topology of the skeleton and skelXforms. The numPoints corresponds to the number of points computed by UsdSkelImagingComputeBoneTopology.

USDSKELIMAGING_API bool UsdSkelImagingComputeBonePoints ( const UsdSkelTopology topology,
const GfMatrix4d jointSkelXforms,
GfVec3f points,
size_t  numPoints 
)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

USDSKELIMAGING_API bool UsdSkelImagingComputeBoneTopology ( const UsdSkelTopology skelTopology,
HdMeshTopology meshTopology,
size_t *  numPoints 
)

Compute mesh topology for imaging skelTopology. The number of points that the mesh is expected to have are return in numPoints.
