* swrast: define, use SWRAST_MAX_WIDTH/HEIGHTBrian Paul2012-02-241-1/+1
| | | | We'll get rid of MAX_WIDTH, MAX_HEIGHT soon.
* swrast: remove MAX_WIDTH arrays in s_copypix.cBrian Paul2012-02-241-5/+20
|
* swrast: use swrast_renderbuffer instead of gl_renderbufferBrian Paul2012-01-241-3/+7
|
* swrast: stop using Put/GetRow/Values() in swrast codeBrian Paul2012-01-241-0/+47
| | | | | All color buffer rendering is now done by accessing mapped renderbuffer memory. We're now able to get rid of all the GetRow/PutRow stuff.
* swrast: remove dstType param from _swrast_read_rgba_span()Brian Paul2012-01-241-2/+2
| | | | It was always GL_FLOAT.
* swrast: Fix use of uninitialized value in rbmapping changes.Eric Anholt2012-01-061-1/+1
| | | | | | | | | I'm so surprised that gcc didn't catch this that I feel like I must be misreading. srcMap is what we initialize (along with dstMap) from this map value right after this check. Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Brian Paul <[email protected]>
* swrast: Use the fast copypixels code to implement fast glBlitFramebuffer().Eric Anholt2012-01-061-6/+7
| | | | | | | | They were meaning to do the same thing of memcpying rows, so just write the code once. Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Brian Paul <[email protected]>
* swrast: Move the check for fast_copy_pixels() ability to caller.Eric Anholt2012-01-061-9/+5
| | | | | | | | I'm going to reuse this function from glBlitFramebuffer() handling, which wants to do the same thing. Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Brian Paul <[email protected]>
* swrast: remove the copy_depth_stencil_pixels() functionBrian Paul2011-12-241-178/+3
| | | | | | | | | Hopefully glCopyPixels(GL_DEPTH_STENCIL) will be handled by the fast copy function. Otherwise, just do the copy with separate depth + stencil copies. That's effectively what the removed code did anyway. Reviewed-by: Eric Anholt <[email protected]>
* swrast: stop using depth/stencil wrappers in CopyPixels codeBrian Paul2011-12-241-8/+21
| | | | | | | | | | | The functions that read depth/stencil values understand all (packed) depth/stencil buffer formats now so there's no reason to use the wrappers. Also, improve the format checks in fast_copy_pixels() to catch mismatched depth/stencil cases. v2: fix the test for combined depth+stencil buffers, per Eric.
* swrast: do fast_copy_pixels() with Map/UnmapRenderbuffer()Brian Paul2011-12-241-43/+89
| | | | | | v2: use memmove() instead of memcpy() in case of overlap Reviewed-by: Eric Anholt <[email protected]>

* mesa: Remove EXT_histogram.Eric Anholt2010-09-231-22/+18
| | | | This has always been optional, and not useful.

* 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...

* 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.
