* mesa: consolidate PBO map/unmap helpersBrian Paul2009-09-031-2/+2
| | | | | | | Instead of _mesa_map_readpix_pbo() use _mesa_map_pbo_source(). Instead of _mesa_map_drawpix_pbo() and _mesa_map_bitmap_pbo() use _mesa_map_pbo_dest().
* swrast: Set vp_override flag during DrawPixelsNicolai Haehnle2009-02-181-0/+11
| | | | | | | | | 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 <[email protected]>
* swrast: fix typo: s/drapix/drawpix/Brian Paul2009-02-091-1/+1

* swrast: replace RENDER_START/FINISH macros with inline functionsBrian Paul2009-01-301-5/+5
|
* mesa: remove unneeded s_drawpix.h headerBrian2008-09-181-1/+0
|
* 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...
* mesa: Call RENDER_FINISH on the zero pixel case.Xiang, Haihao2008-05-081-1/+3
|
* Refactor PBO validate/map code.Brian2008-03-211-2/+1
| | | | We always need to do PBO validation, so do that in core Mesa before calling driver routine.
* add a number of PBO validate/map/unmap functionsBrian2008-03-211-27/+5
| | | | Helper functions for (some) drivers, including swrast.
* Fix some issues with glDrawBuffer(GL_NONE), bug 14198Brian2008-01-221-1/+6
| | | | | Set _ColorDrawBuffers[0] = NULL if no renderbuffers enabled. Check that _ColorDrawBuffers[0] is non-null before dereferencing in a few places.
* Simplify ctx->_NumColorDrawBuffers, _ColorDrawBuffers and fix bug 13835.Brian2008-01-061-3/+3
| | | | | | | | | | | 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 mismatched map/unmap of buffers in swrast read/drawpixels error paths.Eric Anholt2007-12-181-4/+4
|
* Change float depthScale param to _mesa_unpack_depth_span() to GLuint depthMax.Brian2007-07-081-3/+3
|
* use _mesa_unpack_stencil_span() in draw_stencil_pixels(), bug 11457Brian2007-07-031-6/+5
|
* simplify INIT_SPAN codeBrian2007-06-291-4/+9
|
* Undo some prev glDraw/CopyPixel changes which fixed a bug in which colors ↵Brian2007-06-291-11/+4
| | | | | | | 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.Brian2007-06-211-4/+13
| | | | | | | | | | 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.Brian2007-05-201-34/+9
| | | | | 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
|
* 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.
