GeometryReader::getBlendShapeTargetVertexIndices

Vertex position indices affected by the referenced blend shape target.

Windows

MacOS

Linux

Warnings

meshIndex must be less than the value returned by getMeshCount.
blendShapeTargetIndex must be less than the value returned by getBlendShapeTargetCount. @note The vertex position indices are stored in the same order as the deltas they are associated with. These indices can be used to query the associated vertices themselves through getVertexPosition.

Syntax

ConstArrayView< std::uint32_t > getBlendShapeTargetVertexIndices
(
std::uint16_t meshIndex,
std::uint16_t blendShapeTargetIndex
) const

Remarks

MeshIndex must be less than the value returned by getMeshCount.

blendShapeTargetIndex must be less than the value returned by getBlendShapeTargetCount. @note The vertex position indices are stored in the same order as the deltas they are associated with. These indices can be used to query the associated vertices themselves through getVertexPosition.

Returns

View over the list of vertex position indices.

Parameters

Parameter	Description
meshIndex	A mesh's position in the zero-indexed array of meshes.
blendShapeTargetIndex	A position in the zero-indexed array of blend shape targets within the specified mesh.
