This chapter describes how to build primitive geometric shapes.
The Shape node contains Appearance and geometry.
Geometry primitive nodes of interest include Box, Cone, Cylinder, Sphere, Text and FontStyle.
Multiple Shape nodes can be drawn together to make new objects of interest.
These X3D scenes are adapted directly from the
original VRML 2.0 Sourcebook chapter examples.
