public abstract class AbstractSurface

extends java.lang.Object

implements Surface

AbstractSurface is an abstract implementation of Surface that takes care of all of the standard methods of Surface that are shared by all Surface implementations in the same way. By default the location is at the origin, the size is 1.0, and the color is black. Also, an AbstractSurface uses a DiffuseShader by default.
