Detailed Description

Data to determine sub shape contributions.

Sub shape:

A sub shape consists of offsets for a subset of points or all points of a deformable prim with SkelBindingAPI.

The offsets ultimately applied to the prim are computed as linear combination of the sub shapes.

Sub shapes come from the BlendShape prim's targeted by the deformable prim. Each BlendShape can provide several subshapes: one from BlendShape.offsets and several from BlendShape.inbetweens:BETWEEN_NAME:offsets.

Member Data Documentation

subShapeIndex

int subShapeIndex

Index to sub shape. -1 if this pair does not correspond to a sub shape.

Definition at line 50 of file blendShapeData.h.

weight

float weight

Weight authored for BlendShape.inbetweens:BETWEEN_NAME.

weight = 1.0 for the sub shape corresponding to a BlendShape.offsets.

If weight = 0.0, this pair does not correspond to any sub shape and subShapeIndex = -1.
