| * swrast: add missing call to _swrast_depth_bounds_test()Brian Paul2010-01-151-0/+7
| | | | | | | | | | | | | | | | We were calling this from the CI span function, but not the RGBA span function. I don't know of a test program for the GL_EXT_depth_bounds_test extension...

| * swrast: use different temp array in _swrast_get_dest_rgba()Brian Paul2009-12-311-7/+3
| | | | | | | | | | When using multiple color drawbuffers with blending/logicop/masking we were overwriting color values which we still needed.
* | mesa: implement per-buffer color maskingBrian Paul2009-12-291-4/+4
| | | | | | | | | | | | | | | | | | | | | | This is part of the GL_EXT_draw_buffers2 extension and part of GL 3.0. The ctx->Color.ColorMask field is now a 2-D array. Until drivers are modified to support per-buffer color masking, they can just look at the 0th color mask. The new _mesa_ColorMaskIndexed() function will be called by glColorMaskIndexedEXT() or glColorMaski().
* | mesa: per-buffer blend enabled flagsBrian Paul2009-12-291-1/+1
|/ | | | | | | | | | | | | | | ctx->Color.BlendEnabled is now a GLbitfield instead of a GLboolean to indicate blend on/off status for each color/draw buffer. This is infrastructure for GL_EXT_draw_buffers2 and OpenGL 3.x New functions include _mesa_EnableIndexed(), _mesa_DisableIndexed(), and _mesa_IsEnabledIndexed(). The enable function corresponds to glEnableIndexedEXT() for GL_EXT_draw_buffers2 or glEnablei() for GL3. Note that there's quite a few tests for ctx->Color.BlendEnabled != 0 in drivers, etc. Those tests can remain as-is since the mask will be 0 or ~0 unless GL_EXT_draw_buffers2 is enabled.
* mesa: Mostly fix swrast's ARB_depth_clamp support.Eric Anholt2009-10-291-3/+7
| | | | | | | I'd written a testcase for the hard part of the extension enablement, so naturally the easy stuff was completely broken. There are still issues, as I'm seeing FLOAT_TO_UINT(max_f) == 0x0 when max_f == 1.0, but it gets piglit depth-clamp-range closer to success.
* mesa/main: New feature FEATURE_queryobj.Chia-I Wu2009-09-301-4/+0
| | | | | It merges FEATURE_ARB_occlusion_query and FEATURE_EXT_timer_query, and follows the feature conventions.
* mesa: Add support for ARB_depth_clamp.Eric Anholt2009-09-081-0/+3
| | | | | This currently doesn't include fixing up the cliptests in the assembly paths to support ARB_depth_clamp, so enabling depth_clamp forces the C path.
* swrast: always do span clipping in _swrast_write_rgba_span()Brian Paul2009-06-031-14/+4
| | | | | | | | 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.
* swrast: fix span clipping bugBrian Paul2009-05-071-20/+64
| | | | | If a horizontal span of pixels was located at x < 0 we could sometimes read/write outside of renderbuffer bounds.
* swrast: restore !shader check around add_specular()Brian Paul2009-04-071-4/+6
| | | | Fixes a regression from commit 76ac75af8e5481b498981c133836efa2101be2dc.
* swrast: fix secondary color add for glBitmapBrian Paul2009-04-061-2/+2
| | | | | Also, clean up the logic involved in choosing per-vertex vs. per-fragment primary+secondary color addition.
* 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.
* 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: use Stencil._Enabled field instead of Stencil.EnabledBrian Paul2009-03-021-4/+4
|
* swrast: use _EnabledCoordUnits for fixed-function texturingBrian Paul2009-03-021-2/+2
| | | | | | | 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: prefix a bunch of #include lines with "main/".Brian Paul2008-09-181-6/+6
| | | | | This is another step toward removing a whole bunch of -I flags from the cc commands. Still need to address driver code...
* Updated GLSL uniform/sampler handling from gallium-0.1 branchBrian Paul2008-05-141-1/+0
| | | | | | | | | | Previously, the shader linker combined the uniforms used by the vertex and fragment shaders into a combined set of uniforms. This made the implementation of glUniform*() simple, but was rather inefficient otherwise. Now each shader gets its own set of uniforms (no more modelview matrix showing up in the fragment shader uniforms, for example). cherry-picked by hand from gallium-0.1 branch

* Simplify ctx->_NumColorDrawBuffers, _ColorDrawBuffers and fix bug 13835.Brian2008-01-061-80/+81
| | | | | | | | | | | These fields are no longer indexed by shader output. Now, we just have a simple array of renderbuffer pointers. If the shader writes to gl_FragData[i], send those colors to the N _ColorDrawBuffers. Otherwise, replicate the single gl_FragColor (or the fixed-function color) to the N _ColorDrawBuffers. A few more changes and simplifications can follow from this...

* Another round of fixing attribute interpolation for glDraw/CopyPixels.Brian2007-06-211-8/+8
| | | | | | | | | | Need to turn off FRAG_BIT_COL0 in swrast->_ActiveAttribMask when doing glRead/CopyPixels to prevent the user's colors from getting overwritten when a fragment program is active. This was happening in the DRI drivers when MaintainTexEnv program was used (the texenv fragment program was enabled when _swrast_DrawPixels was called). This still isn't an ideal solution, but fixes things for now.

* Overhaul/simplify SWvertex and SWspan attribute handling.Brian2007-05-201-472/+253
| | | | | Instead of separate fog/specular/texcoord/varying code, just treat all of them as generic attributes. Simplifies the point/line/triangle functions.

* Don't allow deferredTexture if using occlusion query and a frag shader.Brian2007-04-191-4/+17
| | | | | | Occlusion query might depend on the shader killing/discarding fragments. Helps fix depth peeling technique. Also, minor tweaks in interpolate_wpos().
