The Voodoo driver uses + * a standard 16bit zbuffer in all cases. It is more consistent + * and now GLQuake and GLQuake2test work also with a GL_ZTRICK 0 + * - the driver is now able to take advantage of the ClipMask[], + * ClipOrMask and ClipAndMask information (under Linux); + * - rewritten the setup_fx_units() function, now the texture + * mapping support is compliant to the OpenGL specs (GL_BLEND + * support is still missing). The LinuxGLQuake console correctly + * fade in/out and transparent water of GLQuake2test works fine + * - written the support for the env. var. FX_GLIDE_SWAPINTERVAL + * - found a bug in the Mesa core.

I'm already rewriting + * this function because it is the source of nearly all the current + * Voodoo driver problems + * - fixed the GLQuake texture misalignment problem (the texture + * coordinates must be scaled between 0.0 and 256.0 and not + * between 0.0 and 255.0) + * - written the support for the GL_EXT_shared_texture_palette + * - some small change for supporting the automatic building of the + * OpenGL32.dll under the Windows platform + * - the redefinition of a mipmap level is now a LOT faster. This path + * is used by GLQuake for dynamic lighting with some call to glTexSubImage2D() + * - the texture memory is now managed a set of 2MB blocks so + * texture maps can't be allocated on a 2MB boundary. The new Pure3D + * needs this kind of support (and probably any other Voodoo Graphics + * board with more than 2MB of texture memory) + * + * Brian Paul ([email protected]) Avid Technology + * - added write_monocolor_span(), fixed bug in write_color_span() + * - added test for stenciling in choosepoint/line/triangle functions + * + * Joe Waters ([email protected]) Aegis + * - written the support for the env. var.

You can + * now define several MB of texture maps also with a 2MB of texture memory + * (the texture memory manager will do automatically all the swap out/swap in + * work). The new texture memory manager has also + * solved a lot of other bugs/no specs compliance/problems + * related to the texture memory usage. The texture + * manager code is inside the new fxmesa3.c file + * - broken the fxmesa.c file in two files (fxmesa1.c and fxmesa2.c) + * and done some code cleanup + * - now is possible to redefine texture mipmap levels already defined + * - fixed a problem with the amount of texture memory allocated for textures + * with not all mipmap levels defined + * - fixed a small problem with single buffer rendering + * + * Brian Paul ([email protected]) Avid Technology + * - read/write_color_span() now use front/back buffer correctly + * - create GLvisual with 5,6,5 bits per pixel, not 8,8,8 + * - removed a few ^M characters from fxmesa2.c file + * + * V0.18 - David Bucciarelli ([email protected]) Humanware s.r.l. + * - the Mesa-2.4beta3 is finally using the driver quads support (the + * previous Mesa versions have never taken any advantage from the quads support !) + * - tested with the Glide 2.4 for Win + * - ported all asm code to Linux + * - ported the v0.18 to Linux (without asm code) + * - back to Linux !!! + * - optimized the SETUP macro (no more vertex snap for points and lines) + * - optimized the SETUP macro (added one argument) + * - the Mesa/Voodoo is now 20/30% for points, lines and small triangles ! + * - performance improvement setting VBSIZE to 72 + * - the GrVertex texture code is now written in asm + * - the GrVertex zbuffer code is now written in asm + * - the GrVertex wbuffer code is now written in asm + * - the GrVertex gouraud code is now written in asm + * - the GrVertex snap code is now written in asm + * - changed the 8bit compressed texture maps in 8bit palette texture maps + * support (it has the some advantage of compressed texture maps without the + * problem of a fixed NCC table for all mipmap levels) + * - written the support for 8bit compressed texture maps (but texture maps with + * more than one mipmap level aren't working fine) + * - finnaly everthing is working fine in MesaQuake ! + * - fixed a bug in the computation of texture mapping coordinates (I have found + * the bug thanks to MesaQuake !) + * - written the GL_REPLACE support (mainly for MesaQuake) + * - written the support for textures with not all mipmap levels defined + * - rewritten all the Texture memory stuff + * - written the MesaQuake support (define MESAQUAKE) + * - working with a ZBuffer if glOrtho or not int the default glDepthRange, + * otherwise working with the WBuffer + * written the glDepthRange support + * + * Diego Picciani ([email protected]) Nova Computer s.r.l. + * - written the fxCloseHardware() and the fxQuaryHardware() (mainly + * for the VoodooWGL emulator) + * + * Brian Paul ([email protected]) Avid Technology + * - implemented read/write_color_span() so glRead/DrawPixels() works + * - now needs Glide 2.3 or later.
