JAVA多媒体开发类库说明

 Shape3D node's list of geometry components with the specified
 geometry component.
 If there are existing geometry components in the list (besides
 the one being replaced), the new geometry component must be of
 the same equivalence class (point, line, polygon, CompressedGeometry,
 Raster, Text3D) as the others.
