* 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 and again in version 6.1 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.
-
* Compiling
-Requirements:
- - gcc version 2.95.3 for BeOS
- You can find it here: http://www.bebits.com/app/2157
+Since Mesa 6.x, it can be build under BeOS with both the R5 builtin gcc version
+or more recent gcc versions available for BeOS, like this gcc version 2.95.3 for BeOS
+you can find at http://www.bebits.com/app/2157.
+Anyway, keep in mind that to take full advantage of Mesa x86 optimizations, you better
+want to use gcc 2.95.3 or sooner versions...
+
+To build Mesa-powered BeOS libGL.so version, open an Terminal window,
+move to Mesa root folder and type this command:
+
+$ make beos
+
+Note that the "beos" argument is only needed the first time to setup build config.
+Next times, typing "make" will be enough.
-Move to the Mesa-4.x src sub-directory and then type "make -f Makefile.BeOS-R5".
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 lib/ directory, along libglut.so library.
+Several demo/test programs should have been build too under progs/* folders.
+If it stop when building one of the progs/* programs, you may want to ignore it
+and force make to move on next target by adding the -k make option:
+
+$ cd progs
+$ make -k
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.
+
+To build a DEBUG version, type instead this :
+
+$ DEBUG=1 make
* Example Programs
-Look in the Mesa-4.x/BeOS/ directory for one or two BGLView demo
-programs. They should have been compiled along with the Mesa
-library.
+Look under progs/beos/ for some BGLView-based programs.
+You should find under progs/samples and progs/redbook directories GLUT-based programs too.
+They all should have been compiled along with the Mesa library.
* GLUT
-A beta version of GLUT 3.7 port for BeOS can be found at
+A beta version of GLUT 3.7 port for BeOS, made by Jake Hamby, can be found at
http://anobject.com/jehamby/Code/Glut-3.7-x86.zip.
+This is the version currently included in Mesa source code, and
+build in lib/libglut.so.
-There's is a 2.5 version in src-glut.beos/, too.
-The original distribution can be obtained from
-http://home.beoscentral.com/jehamby/Glut-3.5-x86.zip
+A previous 3.5 version of this GLUT BeOS port used to be available at
+http://home.beoscentral.com/jehamby/Glut-3.5-x86.zip.
-They are special version of GLUT adapted for the BeOS. I don't
+They're special versions of GLUT for the BeOS platform. I don't
believe Mark Kilgard's normal GLUT distribution includes BeOS
support.
cause a fatal error when running with Be's OpenGL.

* Work Left To Do
-BDirectWindow single buffering support is not implemented yet.
+- BDirectWindow single buffering support is not implemented yet.
+- Color index mode is not implemented yet.
+- Reading pixels from the front buffer not implemented yet.
+- There is also a BGLScreen class in BeOS for full-screen OpenGL rendering.
+ This should also be implemented for Mesa.
+- Multiple renderers add-ons support, first step toward hardware acceleration
+ support.
-Color index mode is not implemented yet.

-* Old BeOS Driver
+* Older 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.
-The Glide library hasn't been updated for BeOS R4, to my knowledge, as
-of February, 1999.
