2009-09-21swrast: fix cube face selectionBrian Paul
If arx and ary are equal, we still want to choose from one of them, and not arz. This is the same as Michal's softpipe fix.
2009-08-31swrast: fix selection/feedback regressionBrian Paul
This fixes a conform selection/feedback regression introduced by commit 8f4d66c5f893b49eb3973aa3b31a856314c045c7
2009-08-31swrast: can't use deferred texture/shading if using KIL instructionBrian Paul
If the fragment program uses KIL, we have to execute it before z/stencil testing. Otherwise, deferred texture/shading lets us skip shading for pixels that fail z/stencil testing.
2009-08-27swrast: fix incorrect tri culling in selection/feedback mode.Brian Paul
See bug 16866.
2009-08-05mesa: make _mesa_clip_blit() a shared functionBrian Paul
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.
2009-05-07swrast: 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
2009-02-09swrast: use ASSIGN_4V() macroBrian Paul
2009-02-09swrast: fix typo: s/drapix/drawpix/Brian Paul
