GeometryWriter::setBlendShapeTargetVertexIndices

Vertex position indices affected by the specified blend shape target.

Windows

MacOS

Linux

Warnings

The vertex position indices must be stored in the same order as the deltas they are associated with.

Syntax

void setBlendShapeTargetVertexIndices
(
    std::uint16_t meshIndex,
    std::uint16_t blendShapeTargetIndex,
    const std::uint32_t * vertexIndices,
    std::uint32_t count
)

Remarks

The vertex position indices must be stored in the same order as the deltas they are associated with.

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.
vertexIndices	The source address from which the vertex position indices are to be copied.
count	The number of vertex position indices to copy. @note Both the mesh storage itself and it's blend shape target storage will be implicitly resized (if needed) to provide storage for the number of meshes and/or blend shape targets that are inferred from the specified indexes.
