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

2009-02-06swrast: return (0,0,0,1) when sampling incomplete textures, not (0,0,0,0)Brian Paul
Fixes piglit shaders/fp-incomplete-tex test.

2009-01-28mesa: remove GL_SGIX_shadow, GL_SGIX_shadow_ambient and GL_SGIX_depth_textureBrian Paul
Everyone should be using the newer/better ARB versions of these extensions.
2009-01-28mesa: implement texture swizzling in swrastBrian Paul
And enable GL_EXT_texture_swizzle for software drivers.

2009-01-23Track two sets of back-face stencil stateIan Romanick
Track separate back-face stencil state for OpenGL 2.0 / GL_ATI_separate_stencil and GL_EXT_stencil_two_side. This allows all three to be enabled in a driver. One set of state is set via the 2.0 or ATI functions and is used when STENCIL_TEST_TWO_SIDE_EXT is disabled. The other is set by StencilFunc and StencilOp when the active stencil face is set to BACK. The GL_EXT_stencil_two_side spec has more details. http://opengl.org/registry/specs/EXT/stencil_two_side.txt

2009-01-21swrast: fix redundant texture application in affine_textured_triangle().Brian Paul
This function does simple texture mapping so disable normal texture mapping before we call _swrast_write_rgba_span() so that we don't do it twice.
2009-01-20mesa: silence uninitialized var warningsBrian Paul
2009-01-09mesa: Remove _Active and _UseTexEnvProgram flags from fragment programs.Eric Anholt
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 <brianp@vmware.com>

2008-10-01Unify ARB_depth_texture and SGIX_depth_textureIan Romanick
The ARB extension is a superset of the older SGIX extension. Any hardware that can support the SGIX version can also support the ARB version. In Mesa, any driver that supports one also supports the other. This unification just simplifies some bits of code.
