hi, new to opengl. was looking for a thin o-o wapper aound the opengl api that would help organize one’s code. i know there are things like inventor, but was looking for something more simple (this is for a class i will be teaching).

thanks

OpenGeometry is a decent package for people that are first getting acquainted with computer graphics. They provide an OO layer on GL, and the authors distribute the source code on CD with their book.
