This chapter describes
how to position shapes within an X-Y-Z world coordinate system by adding a parent Transform node.
Rotations about each axis are counter-clockwise using the right-hand rule.
Nested Transform nodes can translate, rotate and scale shapes relative to each other in 3D space.
These X3D scenes are adapted directly from the
original VRML 2.0 Sourcebook chapter examples.
