Mesa / BeOS Information Introduction Mesa 3.1 features a new driver for the BeOS. The new driver implements a clone of the BGLView class. This class, derived from BView, allows OpenGL rendering into a BeOS window. Any application which uses the BGLView should be able to use Mesa instead of Be's OpenGL without changing any code. Since Be's OpenGL implementation (as of R4) is basically just the SGI sample implementation, it's pretty slow. You'll see that Mesa is considerably faster. Source Code The source code for the driver is in Mesa-3.1/src/BeOS/GLView.cpp It's not 100% finished at this time but many GLUT-based demos are working. Specifically, color index mode isn't implemented at all. No optimizations have been made at this time. Any volunteers? Compiling Simply cd to the Mesa-3.x directory and type "make beos-r4". When it finishes the libMesaGL.so and libMesaGLU.so libraries for BeOS will be in the Mesa-3.x/lib/ directory. Example Programs Look in the Mesa-3.x/BeOS/ directory for one or two BGLView demo programs. They should have been compiled along with the Mesa library. GLUT It seems that you have to recompile GLUT with libMesaGL.so instead of libGL.so in order for everything to work. I'm not sure why. In any case, you'll have to download and compile GLUT for BeOS and put libglut.so in the Mesa-3.x/lib/ directory before you can compile the demos/, samples/ and book/ programs. GLUT for BeOS can be found at: ??? fill-in ??? This is a special version of GLUT adapted for the BeOS. I don't believe Mark Kilgard's normal GLUT distribution includes BeOS support. Old BeOS Driver Mesa 2.6 had an earlier BeOS driver. It was based on Mesa's Off-screen rendering interface, not BGLView. If you're interested in the older driver you should get Mesa 2.6. BeOS and Glide Mesa 3.0 supported the 3Dfx/Glide library on Beos. Download Mesa 3.0 if interested. Ideally, the 3Dfx/Glide support should be updated to work with the new Mesa 3.1 BGLView implementation. ---------------------------------------------------------------------- $Id: README.BEOS,v 1.3 1999/02/06 06:32:20 brianp Exp $
