High-level simple geometry utility primitives for quickly making a scene graph
with.
Implementation Details
Most of the primitives are direct extensions of the
{@link org.j3d.aviatrix3d.Shape3D} class that fill in the geometry part of the
node, leaving the appearance settings up to the user. Some, however, do take
lower-level approach making use of the OpenGL evaluators to work on the
Bezier patches.
