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. - -Since Be's OpenGL implementation (as of R5) 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 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 - -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. - -When it finishes the Mesa based libGL.so library for -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/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. -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 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, 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. - -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're special versions of GLUT for the BeOS platform. I don't -believe Mark Kilgard's normal GLUT distribution includes BeOS -support. - - -* Special Features - -Mesa's implementation of the BGLView class has an extra member -function: CopySubBufferMESA(). It basically works like SwapBuffers() -but it only copies a sub region from the back buffer to the front -buffer. This is a useful optimization for some applications. -If you use this method in your code be sure that you check at runtime -that you're actually using Mesa (with glGetString) so you don't -cause a fatal error when running with Be's OpenGL. - - -* Work Left To Do - -- 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. - -* Other contributors to this BeOS port - -Jake Hamby jhamby <at> anobject <dot> com -Marcin Konicki ahwayakchih <at> neoni <dot> net -Francois Revol revol <at> free <dot> fr -Nathan Whitehorn nathanw <at> uchicago <dot> edu - - -* 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 and newer, to my knowledge, -as of February, 1999. - - ----------------------------------------------------------------------- |
