* Introduction
Mesa 4.1 features a driver for the BeOS. The driver implements
a clone of the BGLView class. This class, derived from BView, allows
OpenGL rendering into a BeOS window.
The 4.1 BeOS driver is an update of Brian Paul's BeOS driver released in Mesa 3.1.
Brian Paul added in Mesa 3.1 a driver for BeOS R4.5 operating system.
This driver implements a clone of the BGLView class. This class, derived from BView, allows
OpenGL rendering into any BeOS window.
His driver was updated in Mesa 4.1 by Philippe Houdoin,
who's maintaining this driver since.
Any application which uses the BGLView should be able to use Mesa
instead of Be's OpenGL without changing any code.
@ -18,10 +19,9 @@ 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-4.1/src/BeOS/ directory.
The source code for the driver is in src/mesa/drivers/beos/ directory.
It's not 100% finished at this time but many GLUT-based demos are
working. No optimizations have been made at this time.

Move to the src/mesa sub-directory and then type "make -f Makefile.BeOS".
When it finishes the Mesa based libGL.so library for
BeOS will be in the Mesa-4.x/src/obj.{x86|ppc}/ directory.
BeOS will be in the src/mesa/src/obj.{x86|ppc}/ directory.
To install it as Be's default libGL.so replacement, put it in your

/boot/home/config/lib/ directory. All your GL/GLUT apps will use
the Mesa based then.
By default, it build a non-debug version library.
The x86 (MMX, SSE and 3DNOW) optimizations are also supported for x86 target.
Sorry, Mesa don't have ppc (Altivec) optimizations yet.
For PowerPC BeOS flavor, sorry, Mesa don't have ppc (Altivec) optimizations yet.
* Example Programs
Look in the Mesa-4.x/BeOS/ directory for one or two BGLView demo
Look in the progs/beos/ directory for one or two BGLView demo
programs. They should have been compiled along with the Mesa
library.
