* A bit of an overhaul of the fog code.Brian Paul2004-02-171-0/+10
| | | | | | glFogCoord didn't always work reliably. ARB fragment program fog options work now. Per-fragment fog computations are now perspective corrected.

| | | | explicit casts and/or tweaking constant and variable definitions.
* Removed all RCS / CVS tags (Id, Header, Date, etc.) from everything.Ian Romanick2003-06-051-3/+0
|
* Added ctx->Texture._EnabledCoordUnits bitfield.Brian Paul2003-04-081-2/+2
| | | | | | Fixed some vertex array / vertex program glitches with glDrawElements. Fixed some fragment program runtime bugs. Non-trivial Cg programs are running now.

|

|
* First batch of code for GL_NV_fragment_program.Brian Paul2003-01-141-13/+13
| | | | | Re-org of some GL_NV_vertex_program code. Replace MAX_TEXTURE_UNITS with MAX_TEXTURE_COORD_UNITS and MAX_TEXTURE_IMAGE_UNITS.
* moved function declaration into the template, define the NAME to specify the ↵Brian Paul2002-11-131-5/+9
| | | | function names
* patches from Gerk Huisma for float-channel renderingBrian Paul2002-10-171-3/+3
|
* finished up GL_EXT_stencil_two_sideBrian Paul2002-10-021-1/+2
|
* re-check-in - something didn't work on the previous check-inBrian Paul2002-08-071-164/+164
|
* Allocate a sw_span struct in the swrast context instead of allocating itBrian Paul2002-04-191-164/+164
| | | | | on the stack frame in the point/line/triangle functions. (Klaus Niederkrueger) This should solve the performance problem Karl found on Windows.
* Klaus Niederkrueger's latest changes: use INIT_SPAN() to init span primitiveBrian Paul2002-04-121-2/+2
| | | | type, width, interp mask and array mask.
* New mipmap lambda calculation. Previously, trilinear filtering couldBrian Paul2002-03-161-92/+57
| | | | | result in _very_ blurry textures. Still need to do some optimization of the new code in s_span.c
* silence gcc warnings (Marc La France)Brian Paul2002-03-011-14/+15
|
* Still more texture/span simplification and clean-up.Brian Paul2002-01-281-9/+19
| | | | Updated comments, fixed indentation, etc.
* More span improvements. Removed _mesa_write_monocolor_span().Brian Paul2002-01-281-3/+2
| | | | | Removed last of span.filled* flags and Klaus's macros. More simplification of triangle functions.
* LOTS of changes, building upon Klaus's work.Brian Paul2002-01-271-16/+18
| | | | | struct sw_span is used throughout span/fragment processing. This is leading to less code and more chances for optimization.
* added some debug printfs (disabled)Brian Paul2001-12-171-1/+8
|
* first checkpoint commit of Klaus's new span code (struct sw_span)Brian Paul2001-12-171-5/+7

|
* replaced some tabs with spacesBrian Paul2001-09-131-94/+94
|

|
* Applied Klaus Niederkrueger's latest flat-shading clean-ups and some of my own.Brian Paul2001-07-261-85/+165

|
* New triangle rasterization code. Store per-span initial/step values in theBrian Paul2001-05-141-268/+299
| | | | | new triangle_span struct. Much cleaner code and possibilities for future optimizations.
