Package Vrml2Sourcebook.Chapter07ScalingShapes

package Vrml2Sourcebook.Chapter07ScalingShapes

Scale transformations grow or shrink a local coordinate system by a scaling factor in the X, Y, and Z directions.

Sometimes scale values are used to adjust units when the data in child nodes is not based on meters. 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.

This X3D VRML2 Sourcebook Chapter 07 Scaling Shapes examples archive is online.

The X3D Java Scene Access Interface (x3djsail) package provides concrete classes for each X3D node and statement.
