2009-06-16mesa: fix REMAINDER() macroBrian Paul
The results were incorrect for some negative values of A. See bug 21872.

2009-06-10swrast: fix state validation bug for changing program constantsBrian Paul
Add _NEW_PROGRAM_CONSTANTS to _SWRAST_NEW_DERIVED. This makes sure that we update the fragment shader's constants when state vars (such as point size) changes. Fixes the progs/glsl/points.c demo.
2009-06-03swrast: always do span clipping in _swrast_write_rgba_span()Brian Paul
It's possible for mis-behaving vertex programs to produce vertex data with very large/NaN values. This doesn't get handled reliably by the clipper code so we may try to rasterize triangles that extend beyond the viewport/window. Always clip spans to avoid invalid memory accesses later.
2009-05-12swrast: update/restore the opt_sample_rgb/rgba_2d() functionsBrian Paul
2009-05-07mesa: move the NullBufferObj from GLcontext to gl_shared_stateBrian Paul
Since shared array objects may point to the null/default buffer object, the null/default buffer object should be part of the shared state.
2009-05-07swrast: fix span clipping bugBrian Paul
If a horizontal span of pixels was located at x < 0 we could sometimes read/write outside of renderbuffer bounds.
2009-04-28swrast: add missing break in clamp_rect_coord_linear()Brian Paul
See bug 21461.
2009-04-21swrast: simplify state update logic for fragment shader const buffersBrian Paul
2009-04-20swrast: fix pointer arithmetic error in get_texel_array()Brian Paul
This came from commit 1b2ab023673261b4b942e1126c0b599d02fbd4a0
2009-04-09swrast: remove some unneeded CHAN_TYPE!=GL_FLOAT codeBrian Paul
2009-04-07swrast: fix point rendering function selectionBrian Paul
Need to clamp default point size to min/max range before checking if it's one. Fixes glean pointAtten test.
2009-04-07swrast: restore !shader check around add_specular()Brian Paul
Fixes a regression from commit 76ac75af8e5481b498981c133836efa2101be2dc.
2009-04-06swrast: more texcombine clean-upsBrian Paul
2009-04-06swrast: asst. clean-ups in texcombine codeBrian Paul
2009-04-06swrast: fix secondary color add for glBitmapBrian Paul
Also, clean up the logic involved in choosing per-vertex vs. per-fragment primary+secondary color addition.
2009-04-06swrast: fix incorrect arithmetic for GL_ADD_SIGNED/GL_COMBINE4_NV modeBrian Paul
2009-04-06swrast: fix texture border color interpretationBrian Paul
The texture border color must be interpreted according to the texture's base format. For example, for a GL_ALPHA texture, sampling the border color should return (0,0,0,borderAlpha). This wasn't an issue here until I removed the legacy texenv code (we always use the combiner path now).
2009-04-03mesa: remove the noClamp parameter to _mesa_pack_rgba_span_float()Brian Paul
It was only set to GL_TRUE in one place where it isn't really needed (glGetTexImage(sRGB format)).
2009-04-01swrast: remove unused integer lerp functionsBrian Paul
2009-04-01swrast: remove old texture_apply() code; always use texture combine codeBrian Paul
2009-04-01swrast: fix bad optimization checkBrian Paul
2009-04-01swrast: remove unused parameterBrian Paul
2009-04-01swrast: minor improvements, clean-ups in texcombine codeBrian Paul
2009-04-01swrast: use float4_array typedef to simplify the code a bitBrian Paul
2009-04-01mesa: texture combine clean-upsBrian Paul
Use MAX_COMBINER_TERMS instead of 4. Rename some vars. Update comments.
2009-04-01swrast: refactor depth/shadow sampling codeBrian Paul
2009-04-01swrast: general clean-up of texture combine codeBrian Paul
2009-04-01swrast: do texture sampling/combining in floating pointBrian Paul
The code's cleaner and a step toward supporting float-valued texture sampling. Some optimizations for common cases can be added and re-enabled...
2009-04-01swrast: fix glDrawBuffer(GL_FRONT_AND_BACK)Brian Paul
We weren't putting the right colors into the back buffer in this mode.
2009-03-28mesa: add new signed rgba texture formatRoland Scheidegger
This is a (partial) backport of the signed texture format support in OGL 3.1. Since it wasn't promoted from an existing extension roll our own.
2009-03-17swrast: use better _swrast_compute_lambda() functionBrian Paul
The MAX-based function can produce values that are non-monotonic for a span which causes glitches in texture filtering. The sqrt-based one avoids that. This is perhaps slightly slower than before, but the difference probably isn't noticable given we're doing software mipmap filtering. Issue reported by Nir Radian <nirr@horizonsemi.com>
2009-03-12mesa: add support for ATI_envmap_bumpmapRoland Scheidegger
add new entrypoints, new texture format, etc translate in texenvprogram.c for drivers using the mesa-generated tex env fragment program also handled in swrast, but not tested (cannot work due to negative texel results not handled correctly)
2009-03-11mesa: remove some last remnants of GL_MESA_program_debugBrian Paul
2009-03-11mesa: remove gl_texture_object::_Function field and associated codeBrian Paul
It was only used in one place in swrast.
2009-03-07swrast: remove old commentBrian Paul
2009-03-07swrast: rename s_buffers.c -> s_clear.cBrian Paul
2009-03-07mesa: remove GL_MESA_program_debug extensionBrian Paul
This was never fully fleshed out and hasn't been used.
2009-03-02mesa: use Stencil._Enabled field instead of Stencil.EnabledBrian Paul
2009-03-02swrast: use _EnabledCoordUnits for fixed-function texturingBrian Paul
Using _EnabledUnits was wrong because it included vertex texture units. This change plus the prev commit fixes occasional failures of glean/glsl1 vertex texture test failure.
2009-03-02mesa: remove unused AUX buffersBrian Paul
Remove all references to aux buffers 1..3. Keep AUX0 around for now just in case, but it'll probably go too someday. I don't know of any OpenGL drivers since the IRIX days that support aux color buffers.
2009-02-28mesa: rename, reorder FRAG_RESULT_x tokensBrian Paul
s/FRAG_RESULT_DEPR/FRAG_RESULT_DEPTH/ s/FRAG_RESULT_COLR/FRAG_RESULT/COLOR/ Remove FRAG_RESULT_COLH (NV half-precision) output since we never used it. Next, we might merge the COLOR and DATA outputs (COLOR0, COLOR1, etc).
2009-02-28mesa: move GLfixed type and related macros to swrast moduleBrian Paul
Fixed point is only used in swrast and sw-based drivers.
2009-02-28mesa: replace FEEDBACK_TOKEN macro with _mesa_feedback_token() inline functionBrian Paul
2009-02-21mesa: use an array for current texture objectsBrian Paul
Use loops to consolidate lots of texture object code.
2009-02-18swrast: Set vp_override flag during DrawPixelsNicolai Haehnle
Obviously, the color of fragments produced by DrawPixels is not constant, even if the current vertex array / vertex program state indicates that the color for normal rendering will be constant. Therefore, we need to override certain optimisations that have been added to texenvprogram.c Signed-off-by: Nicolai Haehnle <nhaehnle@gmail.com>
2009-02-10Merge commit 'origin/gallium-master-merge'Brian Paul
This is the big merge of the gallium-0.2 branch into master. gallium-master-merge was just the staging area for it. Both gallium-0.2 and gallium-master-merge are considered closed now. Conflicts: progs/demos/Makefile src/mesa/main/state.c src/mesa/main/texenvprogram.c
