Shape3D[] shapes)
Each Shape3D in the array must be of the same dimensionality (point, line, or surface) and have the same vertex format as the others. Texture coordinates are ignored.
If a color is specified in the material attributes for a Shape3D then that color is added to the CompressionStream as the current global color. Subsequent colors as well as any colors bundled with vertices will override it. Only the material diffuse colors are used; all other appearance attributes are ignored.

Defaults of 16, 9, and 6 bits are used as the quantization values for positions, colors, and normals respectively. These are the maximum resolution values defined for positions and normals; the default of 9 for color is the equivalent of the 8 bits of RGBA component resolution commonly available in graphics frame buffers.
