OOMaterial.h
4
5
A material which can be applied to an OpenGL object, or more accurately, to
6
the current OpenGL render state.
7
8
This is an abstract class; actual materials should be subclasses.
9
10
Currently, only shader materials are supported. Direct use of textures should
11
also be replaced with an OOMaterial subclass.
