SDL CVS code:
http://www.devolution.com/~slouken/SDL/cvs.html
Recap…
SDL 1.1 contains the following new features:
- OpenGL support
- Joystick support
- Keyboard hotkey support (may be removed in future releases)
- Fullscreen support on BeOS
All features are implemented on all supported platforms, but are not
fully tested. CVS code is for developer testing only and should not
be redistributed.
I will be putting a series of GL tutorials online in a few days,
and they can be a simple introduction to OpenGL using SDL.
There is a new testgl test program which shows how to use SDL with
OpenGL.
If someone wants to add a tutorial, it would be really helpful
to have a tutorial on uploading an SDL surface to a texture, and
then rotating that texture in 3D space.
Enjoy!
