Hi there, I have developed a simulator that works fine demonstrating a 3D performance about an AI control system. So, what I would like to implement now to improve the show time is a user interface with a lot of bottons and so on. Someone know where could I found such information or simple samples to work around it. I have a a dozen of OGL books, and no one talks anything about Frameworks with OGL. Thnx in advance... Best wishes, Thomas

The first decision you have to make is if you want a "real" GUI or something simpler like the ones found in games. The best way to build something fancy is probably by using platform specific code.

You can also try glut with addon libraries like mui. Will not be so pretty but platform independent.
