X3D Example Archives: VRML 2 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.

11 X3D Scenes		Scene Descriptions
	Figure 07.04b Scale 2x With Axes	Scaling up by 2.0 along the X-axis direction and building a sphere, with coordinate axes superimposed to show X3D/VRML directions
	Figure 07.05b Scale 0.5x With Axes	Scaling down by 0.5 along the X-axis direction and building a sphere, with coordinate axes superimposed to show X3D/VRML directions
	Figure 07.06b Scale 2y With Axes	Scaling up by 2.0 along the Y-axis direction and building a sphere, with coordinate axes superimposed to show X3D/VRML directions
