X3D Example Archives: VRML 2 Sourcebook, Chapter 05 Positioning Shapes

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. Also available: Introduction to VRML97 SIGGRAPH98 course notes.
