Hi, For those (if any) who use (or want to use) Ada and OpenGL together, I've been updating my page quite a bit recently and have included some more advanced demos. There is a more up to date NeHe base code than is currently linked to nehe.game.dev.net. It's still not as clean as I'd like, but it is a work in progress. http://www.abyss2.demon.co.uk/projects/ada/index.html Thanks, Luke A. Guest.
