Function Documentation

UsdSkelImagingComputeBoneJointIndices() [1/2]

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.

UsdSkelImagingComputeBoneJointIndices() [2/2]

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.

UsdSkelImagingComputeBonePoints() [1/2]

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.

UsdSkelImagingComputeBonePoints() [2/2]

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.

UsdSkelImagingComputeBoneTopology()

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.
