Geometry is an abstract class that specifies the geometry component information required by a Shape3D node. Geometry objects describe both the geometry and topology of the Shape3D nodes that reference them. Geometry objects consist of four generic geometric types:

• Compressed Geometry
• GeometryArray
• Raster
• Text3D

Each of these geometric types defines a visible object or set of objects. A Geometry object is used as a component object of a Shape3D leaf node.
