Simple renderer in .net with SharpGL (openGL)

[Roland Melkert]

Also make sure you don't forget

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

just before you start drawing stuff (every frame).

Also if you found a tutorial source, I'm sure they offer a basic render loop example which would take care of setting defaults for camera, materials and lighting etc.
