2003-02-27fix float color interpolation (bug 694461)Brian Paul
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.
2002-11-26added missing call to _mesa_write_mono_alpha_span()Brian Paul
2002-11-09fix float->int Z calculation in _mesa_span_default_z()Brian Paul
2002-10-30s/BZERO/_mesa_bzero/Brian Paul
2002-10-24Header file clean-up:Brian Paul
1. Remove all.h and PC_HEADER junk. 2. Rolled mem.c and mem.h into imports.c and imports.h 3. Include imports.h instead of mem.h Restore _mesa_create/initialize_context() to be like they were in 4.0.4 New wrappers for a few std C functions: _mesa_atoi(), _mesa_strstr(), etc.
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.
2002-10-02finished up GL_EXT_stencil_two_sideBrian Paul
2002-09-06GL_EXT_stencil_two_side extension, not 100% complete yet.Brian 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.
2002-07-09Overhaul of glRead/DrawBuffer() code. Now, swrast->Driver.SetBuffer()Brian Paul
indicates the read AND draw color buffer for all software rasterization. Lots of related clean-ups. See RELNOTES-4.1 for details.
2002-06-15Implemented GL_NV_texture_rectangle extension.Brian Paul
Replace struct gl_texure_object's Dimension w/ Target field. Added _EnabledUnits to struct gl_texture_attrib - the _ReallyEnabled field is obsolete, but still present for now. This effectively removes the 8-texture units limit, 32 units now possible, but unlikely! New TEXTURE_1D/2D/3D/CUBE/RECT_BIT tokens for unit->_ReallyEnabled field. Updated device drivers to use ctx->Texture._EnabledUnits.
2002-06-15Added ctx parameter to _mesa_debug()Brian Paul
Added _mesa_printf() Updated SetDrawBuffer() function in all drivers (ala 4.0.3) Import 4.0.3/DRI changes.
2002-05-02Implemented GL_ARB_texture_env_crossbar.Brian Paul
Simplification of some of the texture application code.
2002-04-20fixed Width/Height cut&paste typoBrian Paul
2002-04-19removed a stray debug printfBrian Paul
2002-04-19casts to fix GLint/GLuint mismatchesBrian Paul
2002-04-12Klaus Niederkrueger's latest changes: use INIT_SPAN() to init span primitiveBrian Paul
type, width, interp mask and array mask.
2002-03-16New mipmap lambda calculation. Previously, trilinear filtering couldBrian Paul
result in _very_ blurry textures. Still need to do some optimization of the new code in s_span.c
2002-02-17Simplified fog code.Brian Paul
2002-02-17Optimized the interpolate_texcoords() function:Brian Paul
Use fast approximation to log(). Check for dq==0 to avoid a per-pixel divide.
2002-02-15GL_ARB_window_pos fog fixBrian Paul
2002-02-14minor clean-upBrian Paul
2002-02-06added an assertion, fix typoBrian Paul
2002-02-04Clean-up and remove dead code related to depth/stecil testing.Brian Paul
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.
2002-01-31Clean-up and optimize alpha test code.Brian Paul
Major clean-up of pixel zoom code.
2002-01-28Still more texture/span simplification and clean-up.Brian Paul
Updated comments, fixed indentation, etc.
2002-01-28More span improvements. Removed _mesa_write_monocolor_span().Brian Paul
Removed last of span.filled* flags and Klaus's macros. More simplification of triangle functions.
2002-01-28More span clean-up, mostly texture-related.Brian Paul
_mesa_rasterize_span() is gone, replaced by new _mesa_write_textured_span(). Removed some unneeded triangle functions - more simplification possible.
2002-01-27LOTS of changes, building upon Klaus's work.Brian Paul
struct sw_span is used throughout span/fragment processing. This is leading to less code and more chances for optimization.
