* swrast: replace RENDER_START/FINISH macros with inline functionsBrian Paul2009-01-301-2/+2
|
* mesa: prefix a bunch of #include lines with "main/".Brian Paul2008-09-181-9/+9
| | | | | This is another step toward removing a whole bunch of -I flags from the cc commands. Still need to address driver code...
* Simplify ctx->_NumColorDrawBuffers, _ColorDrawBuffers and fix bug 13835.Brian2008-01-061-2/+2
| | | | | | | | | | | 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...
* fix copypixels overlap test bug (#12417)Brian2007-09-141-2/+9

* simplify INIT_SPAN codeBrian2007-06-291-4/+9
|
* Undo some prev glDraw/CopyPixel changes which fixed a bug in which colors ↵Brian2007-06-291-12/+5
| | | | | | | 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.Brian2007-06-211-3/+11
| | | | | | | | | | 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.Brian2007-05-201-25/+4
| | | | | Instead of separate fog/specular/texcoord/varying code, just treat all of them as generic attributes. Simplifies the point/line/triangle functions.
* Fix color sum bug 10688.Brian2007-04-211-6/+3
|
* as with prev commit, also fix color index mode zoomed depth copies (bug 10608)Brian2007-04-111-1/+1

* fix zoomed depth copies (bug 10608)Brian2007-04-111-2/+1

* fix color storage bug in convolution pathBrian2007-04-051-1/+1
|
* Overlapping copies with zoomZ=-1 were broken. See bug 10521.Brian2007-04-041-47/+47
| | | | | Need to check for overlapping src/dest regions before computing bottom-to-top vs. top-to-bottom order.
* Add _swrast_span_default_secondary_color() for use with glBitmap, ↵Brian2007-03-261-1/+6
| | | | | | | glDrawPixels, etc. Secondary color wasn't getting added to post-texture color when drawing bitmaps, images. See bug 10409.
