If you're looking to write cross-platform games, or want to use OpenGL (and don't want to use the native libraries on your platform for things): you can use SDL for user input, audio, window management, and fonts, but use OpenGL to render 3D images on your screen. It works fine, in fact SDL is designed to support it. -- Matthew Weigel hacker unique@xxxxxxxxxxx --------------------- To unsubscribe go to http://gameprogrammer.com/mailinglist.html
