* Re-implement GLSL texture sampler variables.Brian2007-10-261-0/+2
| | | | | | | | | | GLSL sampler variables indicate which texture unit to use for TEX instructions. Previously, this was baked into the fragment/vertex program and couldn't be readily changed once set. Now, SamplerUnits[] array indicates which texture unit is to be used for each sampler variable. These values are set with glUniform1i(). This is extra state that must be passed to the fragment/vertex program executor at runtime.
* Implement gl_PointCoord attribute for GLSL fragment shaders.Brian2007-10-244-52/+69
| | | | Contains the normalized fragment position within a point sprite.
* check for null swrast (pipe work-around)Brian2007-08-161-0/+3

* fix color interpolation for CHAN_BITS==32Brian2007-07-261-1/+1
|
* don't use rgba_line() if CHAN_BITS==32Brian2007-07-261-1/+5
|
* Remove ctx->Point._Size and ctx->Line._Width.Brian2007-07-213-12/+16
| | | | | | The clamping for these values depends on whether we're drawing AA or non-AA points, lines. Defer clamping until drawing time. Drivers could compute and keep clamped AA and clamped non-AA values if desired.

* Undo some prev glDraw/CopyPixel changes which fixed a bug in which colors ↵Brian2007-06-294-26/+15
| | | | | | | were overwritten by interpolating attributes. Now just set the span->arrayAttribs mask in glDraw/CopyPixels and be sure we don't overwrite the values in interpolate_active_attribs().

* Another round of fixing attribute interpolation for glDraw/CopyPixels.Brian2007-06-213-15/+32
| | | | | | | | | | 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.

* Rework _mesa_update_texture_compare_function() to only be called duringBrian2007-06-111-20/+0
| | | | | | | state validation/update. Note that we're still temporarily skipping the test for an active fragment program. Need to fix shadow2D() ...
* Replace texobj->Complete with texobj->_Complete since it's a derived field.Brian2007-06-111-1/+1
|
* Temporarily disable the calls to _mesa_update_texture_compare_function().Brian2007-06-111-0/+4
| | | | This fixes the depth-peel regression reported by Brad King.
* Add support for GL_ARB_fragment_program_shadow.Ian Romanick2007-06-071-1/+2
|
* Fix ARB_fp spec conformance bug WRT shadow sampling.Ian Romanick2007-06-072-19/+17
| | | | | The ARB_fp (and other assembly-level fragment program specs) say that the depth comparison function is always GL_NONE in fragment program mode.

|
* Overhaul/simplify SWvertex and SWspan attribute handling.Brian2007-05-2025-1976/+1102
| | | | | Instead of separate fog/specular/texcoord/varying code, just treat all of them as generic attributes. Simplifies the point/line/triangle functions.
* Initial implementation of MESA_texture_arrayIan Romanick2007-05-161-63/+748
| | | | | Shadow sampling from texture arrays is still not implemented. Everything else should be there, though.
