Grouping Shapes

• Java3D has a set of nodes to create groups: OrderedGroup, Switch, TransformGroup, etc.

• Java 3D supports numerous utility methods to build and manipulate 4x4 matrices and vectors:

Transform3D yAxis = new Transform3D( );

yaxis.roty( 0.785 );

TransformGroup scene = new TranformGroup( );

scene.addChild( sign );

scene.setTransform( yaxis );
