OGLSkinnedSurfaceShader (object)¶

バージョン 1.12.0 で追加.

The OGLSkinnedSurfaceShader inherits the OGLSurfaceShader. It extends the OGLSurfaceShader for shading skinned geometries. The Skinned geometries should have a SkinningAttribute attribute applied containing the vertex ids and skin weights.

The SkinningAttribute attribute is converted to a packed vec4 struct by the InlineDrawing system. Each element in the vec4 packs an index and weight, enabling up to 4 joints per vertex to be used in the deformation.

注釈

The FbxCharacter loads skinning data from Fbx files. See the FbxCharacter.kl file for examples of generating

注釈

For arbitrary number of joints to be used per vertex, use CPU based skinning. And example of this can be found in the Character.
