* mesa: fix REMAINDER() macroBrian Paul2009-06-161-1/+1
| | | | | The results were incorrect for some negative values of A. See bug 21872.
* swrast: fix state validation bug for changing program constantsBrian Paul2009-06-101-0/+1
| | | | | | | 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.
* swrast: fix span clipping bugBrian Paul2009-05-072-22/+71
| | | | | If a horizontal span of pixels was located at x < 0 we could sometimes read/write outside of renderbuffer bounds.
* swrast: add missing break in clamp_rect_coord_linear()Brian Paul2009-04-281-0/+1
| | | | See bug 21461.
* swrast: simplify state update logic for fragment shader const buffersBrian Paul2009-04-211-25/+2
|
* swrast: fix pointer arithmetic error in get_texel_array()Brian Paul2009-04-201-2/+1
| | | | This came from commit 1b2ab023673261b4b942e1126c0b599d02fbd4a0
* swrast: remove some unneeded CHAN_TYPE!=GL_FLOAT codeBrian Paul2009-04-091-7/+0
|
* swrast: fix point rendering function selectionBrian Paul2009-04-071-1/+4
| | | | | Need to clamp default point size to min/max range before checking if it's one. Fixes glean pointAtten test.
* swrast: restore !shader check around add_specular()Brian Paul2009-04-071-4/+6
| | | | Fixes a regression from commit 76ac75af8e5481b498981c133836efa2101be2dc.
* swrast: more texcombine clean-upsBrian Paul2009-04-061-21/+10
|
* swrast: asst. clean-ups in texcombine codeBrian Paul2009-04-061-26/+19
|
* swrast: fix secondary color add for glBitmapBrian Paul2009-04-063-11/+30
| | | | | Also, clean up the logic involved in choosing per-vertex vs. per-fragment primary+secondary color addition.
* swrast: fix incorrect arithmetic for GL_ADD_SIGNED/GL_COMBINE4_NV modeBrian Paul2009-04-061-6/+6
|
* swrast: fix texture border color interpretationBrian Paul2009-04-061-30/+68
| | | | | | | 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).
* mesa: remove the noClamp parameter to _mesa_pack_rgba_span_float()Brian Paul2009-04-031-2/+2
| | | | | It was only set to GL_TRUE in one place where it isn't really needed (glGetTexImage(sRGB format)).
* swrast: remove unused integer lerp functionsBrian Paul2009-04-011-43/+1
|
* swrast: remove old texture_apply() code; always use texture combine codeBrian Paul2009-04-013-403/+22
|
* swrast: fix bad optimization checkBrian Paul2009-04-011-1/+2
|
* swrast: remove unused parameterBrian Paul2009-04-011-6/+1
|
* swrast: minor improvements, clean-ups in texcombine codeBrian Paul2009-04-011-9/+8
|
* swrast: use float4_array typedef to simplify the code a bitBrian Paul2009-04-011-54/+71
|
* mesa: texture combine clean-upsBrian Paul2009-04-012-74/+68
| | | | | | Use MAX_COMBINER_TERMS instead of 4. Rename some vars. Update comments.
* swrast: refactor depth/shadow sampling codeBrian Paul2009-04-011-262/+271
|
* swrast: general clean-up of texture combine codeBrian Paul2009-04-011-246/+161
|
* swrast: do texture sampling/combining in floating pointBrian Paul2009-04-016-764/+511
| | | | | The code's cleaner and a step toward supporting float-valued texture sampling. Some optimizations for common cases can be added and re-enabled...
* swrast: fix glDrawBuffer(GL_FRONT_AND_BACK)Brian Paul2009-04-011-2/+8
| | | | We weren't putting the right colors into the back buffer in this mode.
* mesa: add new signed rgba texture formatRoland Scheidegger2009-03-281-2/+2
| | | | | 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.
* swrast: use better _swrast_compute_lambda() functionBrian Paul2009-03-171-6/+6
| | | | | | | | | | 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 <[email protected]>
* mesa: add support for ATI_envmap_bumpmapRoland Scheidegger2009-03-121-1/+94
| | | | | | | | 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)
* mesa: remove some last remnants of GL_MESA_program_debugBrian Paul2009-03-112-8/+0
|
* mesa: remove gl_texture_object::_Function field and associated codeBrian Paul2009-03-111-1/+3
| | | | It was only used in one place in swrast.
* swrast: remove old commentBrian Paul2009-03-071-2/+0
|
* swrast: rename s_buffers.c -> s_clear.cBrian Paul2009-03-071-0/+0
|
* mesa: remove GL_MESA_program_debug extensionBrian Paul2009-03-071-6/+0
| | | | This was never fully fleshed out and hasn't been used.
* mesa: use Stencil._Enabled field instead of Stencil.EnabledBrian Paul2009-03-023-6/+6
|
* swrast: use _EnabledCoordUnits for fixed-function texturingBrian Paul2009-03-022-8/+8
| | | | | | | 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.
* mesa: remove unused AUX buffersBrian Paul2009-03-021-4/+1
| | | | | | 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.
* mesa: rename, reorder FRAG_RESULT_x tokensBrian Paul2009-02-282-7/+7
| | | | | | | 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).
* mesa: move GLfixed type and related macros to swrast moduleBrian Paul2009-02-282-0/+34
| | | | Fixed point is only used in swrast and sw-based drivers.
* mesa: replace FEEDBACK_TOKEN macro with _mesa_feedback_token() inline functionBrian Paul2009-02-281-4/+4
|
* mesa: use an array for current texture objectsBrian Paul2009-02-211-5/+10
| | | | Use loops to consolidate lots of texture object code.
* swrast: Set vp_override flag during DrawPixelsNicolai Haehnle2009-02-181-0/+11
| | | | | | | | | 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 <[email protected]>
* Merge commit 'origin/gallium-master-merge'Brian Paul2009-02-102-1/+4

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a note in state.c about _Active deserving to die, and there were potential issues with it due to i965 forgetting to set _UseTexEnvProgram. Removing both simplifies things. Reviewed-by: Brian Paul <[email protected]>
