2006-10-12Lots of changes to support runtime renderbuffer depths.Brian Paul
_swrast_read_rgba_span() now takes a datatype parameter. New optimization for glReadPixels(format=GL_RGB). New glCopyPixels optimization for the simple, common cases.
2006-10-01New SWspan and SWspanarrays typedefs.Brian Paul
2006-09-29more changes for runtime renderbuffer depthsBrian Paul
2006-09-25Initial work for supporting different renderbuffer color depths at runtime.Brian Paul
2006-09-21remove rgb[] array from span_arrays_struct - was only used in a few placesBrian Paul
2006-04-11More GLSL code:Michal Krol
- use macros to access and modify render inputs bit-field; - un-alias generic vertex attributes for ARB vertex calls; - use MAX_VERTEX_PROGRAM_ATTRIBS (NV code) or MAX_VERTEX_ATTRIBS (ARB code) in place of VERT_ATTRIB_MAX; - define VERT_ATTRIB_GENERIC0..15 for un-aliased vertex attributes for ARB_vertex_shader; - fix generic attribute index range check in arbprogparse.c; - interface GLSL varyings between vertex and fragment shader; - use 64-bit optimised bitset (bitset.h) for render inputs;

2006-01-26New comments, clean-up of fields related to point/line/triangle validation.Brian Paul
2005-11-12Added OSMesaColorClamp(), bug 4917Brian Paul
2005-11-08At keithw's request, remove all traces of the "fragment program to C" andIan Romanick
TCC experiment.
2005-09-21replace GLdepth with GLuint and remove GLdepthBrian Paul
2005-09-16change some commentsBrian Paul
2005-09-16Rework the texture filtering functions a bit.Brian Paul
No need to pass the texture unit number as an argument.
2005-09-16more GLuint->GLbitfield changesBrian Paul
2005-09-15Replace GLuint with GLbitfield where appropriate. Also replace GLuintBrian Paul
with GLboolean in a few places.
2005-09-05remove obsolete CurrentBufferBitBrian Paul
2005-09-03Remove last remnants of pre-renderbuffer code.Brian Paul
2005-05-04Major check-in of changes for GL_EXT_framebuffer_object extension.Brian Paul
Main driver impacts: - new code for creating the Mesa GLframebuffer - new span/pixel read/write code Some drivers not yet updated/tested.
2004-12-19Implement software ATI_fragment_shaderDave Airlie
no error detection, slow, may not be 100% correct but a good start
2004-10-13Fix minor fog / fragment program state bug.Brian Paul
Don't add diffuse and specular colors when using fragment program.
2004-09-10More updates for Doxygen.Brian Paul
2004-04-14Use tcc and the emitted C code from s_fragprog_to_c.c to dynamically compileKeith Whitwell
and execute fragment programs. Very limited and experimental, but works well enough to run arbfplight.c. http://fabrice.bellard.free.fr/tcc/ Compile with 'make linux-tcc', being sure to make clean first.
2004-03-21Implemented support for software-based AUX color buffers.Brian Paul
Only available with Xlib driver for now. Assorted clean-ups related to Draw/ReadBuffer(). Renamed FRONT_LEFT_BIT -> DD_FRONT_LEFT_BIT, etc.
2004-02-17A bit of an overhaul of the fog code.Brian Paul
glFogCoord didn't always work reliably. ARB fragment program fog options work now. Per-fragment fog computations are now perspective corrected.
2004-02-17added SPAN_WBrian Paul
2003-10-22More SciTech SNAP updates. Some of these files didn't really change, butKendall Bennett
they show up in the list (GLU stuff) for some reason. The major change here is the addition of code in the glx86asm.py file to generate assembler stub entry points with the correct name decorations for _stdcall calling conventions so this can be used on Windows boxes.

2003-05-01Use ctx->Const.MaxTextureImageUnits and MaxTextureCoordUnits in more places.Brian Paul
Misc vertex array / vertex program changes.
2003-03-16Store partial derivative values in sw_span structure.Brian Paul
Implemented DDX and DDY fragment program instructions (whew!) Not fully tested yet.
2003-02-28minor typoBrian Paul
2003-02-23Move span stuff from swrast.h to s_context.h (it's private).Brian Paul
Implemented remaining fragment program instructions. Initial changes to implement fragment program texture sampling.
2003-01-14First batch of code for GL_NV_fragment_program.Brian Paul
Re-org of some GL_NV_vertex_program code. Replace MAX_TEXTURE_UNITS with MAX_TEXTURE_COORD_UNITS and MAX_TEXTURE_IMAGE_UNITS.
2002-10-29updated email addressesBrian Paul
2002-10-11Another round of glRead/DrawBuffer() clean-ups and simplifications.Brian Paul
Replaced ctx->Color._DriverDrawBuffer with swrast->CurrentBuffer. Replaced ctx->Pixel._DriverReadBuffer with ctx->Pixel._ReadSrcMask. swrast->Driver.SetBuffer() takes FRONT/BACK_LEFT/RIGHT_BIT values now. Added tokens and code for GL_AUX buffers, for completeness.
2002-10-04multiple GL_POINTS can now be rendered together into one fragment spanBrian Paul
2002-08-07struct sw_span is again allocated on the stack, but the arrays of spanBrian Paul
data are broken out into a new struct span_arrays which is allocated per-context (to avoid huge stack allocations - a problem on Windows). This lets us use span.redStep instead of span->redStep (for example) to hopefully get slightly better performance in the triangle functions.
2002-05-02Implemented GL_ARB_texture_env_crossbar.Brian Paul
Simplification of some of the texture application code.
2002-04-19Allocate a sw_span struct in the swrast context instead of allocating itBrian Paul
on the stack frame in the point/line/triangle functions. (Klaus Niederkrueger) This should solve the performance problem Karl found on Windows.
2002-02-02Converted line drawing over to new span code, pb no longer used.Brian Paul
Big clean-up of line drawing code. Removed many obsolete span processing functions.
2002-02-02sw_span can now hold x/y arrays of fragment positions - getting ready toBrian Paul
ditch the pb (pixel buffer) code. Converted point drawing, bitmaps and aa lines to use new span functions.
2002-01-10Klaus's latest patches: change texcoord[3] to texcoord[4] everywhereBrian Paul
2001-12-17first checkpoint commit of Klaus's new span code (struct sw_span)Brian Paul
2001-08-14Fixes for 32-bit GLchans: smooth/flat/textured triangles seem to work now.Brian Paul
2001-07-13assorted changes for supporting GLfloat color channels (not done)Brian Paul

Remove 'swrast->_MultiTexEnabled' derived value.
2001-03-29Removed DD_Z_NEVER.Brian Paul
Replaced SEPERATE with SEPARATE. Renumbered _NEW_ flags. Removed _NEW_COLORTABLE.
