X3D Example Archives: VRML 2.0 Sourcebook, Chapter 07 - Scaling Shapes

Scale grows or shrinks a coordinate system by a scaling factor in X, Y, and Z. Transform operations are bottom-up: children shapes are first scaled, rotated, then translated. Order is fixed, independent of the field order that happens to occur in the Transform node.

These X3D scenes are adapted directly from the original VRML 2.0 Sourcebook chapter examples. Also available: Introduction to VRML97 SIGGRAPH98 course notes.
