* 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.
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.
- gcc version 2.95.3 for BeOS
You can find it here: http://www.bebits.com/app/2157
-Move to the Mesa-4.x src sub-directory and then type "make -f Makefile.BeOS-R5".
+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/GLUTapps will use
+/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.
if interested. Ideally, the 3Dfx/Glide support should be updated to
work with the new Mesa 3.1 BGLView implementation.
-The Glide library hasn't been updated for BeOS R4, to my knowledge, as
+The Glide library hasn't been updated for BeOS R4 and newer, to my knowledge, as
of February, 1999.
