3.41 Shape

Shape {

  exposedField SFNode appearance NULL

  exposedField SFNode geometry   NULL

}

The Shape node has two fields, appearance and geometry, which are used to create rendered objects in the world. The appearance field contains an Appearance node that specifies the visual attributes (e.g., material and texture) to be applied to the geometry. The geometry field contains a geometry node. The specified geometry node is rendered with the specified appearance nodes applied.

"2.14 Lighting model" contains details of the VRML lighting model and the interaction between Appearance and geometry nodes.

If the geometry field is NULL, the object is not drawn.
