I would be interested in hearing specific reasons why we could not extend SceneGraphPath itself rather than introducing a new class. One of the overriding design principles of jReality is expressed in the saying, "Why have two classes when one will do?" For example, can anyone provide a specific exa...

By "icosahedra example" I assume you mean de.jreality.tutorial.Icosahedra. The Icosahedra example has to do with using transparency in jReality.
