* more blending updates from JoseBrian Paul2002-04-021-19/+9

|
* reset span.end to zero after rendering the spanBrian Paul2002-03-281-1/+2

* fixed inequality in an assertionBrian Paul2002-03-271-2/+2
|
* removed a bad assertionBrian Paul2002-03-251-2/+1
|
* Test implementation of proposed GL_EXT_shadow_funcs extension. This justBrian Paul2002-03-231-55/+103
| | | | | generalizes the R/texture comparision operators to include all eight of the depth test comparisons.
* Use MESA_PBUFFER_ALLOC/FREE macros to allocate all framebuffer and textureBrian Paul2002-03-194-19/+20
| | | | | | | memory. These can be overridden by applications which need to manage this memory specially. Contributed by Gerk Huisma. Also, new code for 8-bit -> 16-bit/channel texture image storage which fills in the least-significant bits properly.
* fix Intel C compiler warnings (Gerk Huisma)Brian Paul2002-03-191-3/+3
|
* New mipmap lambda calculation. Previously, trilinear filtering couldBrian Paul2002-03-167-327/+265
| | | | | result in _very_ blurry textures. Still need to do some optimization of the new code in s_span.c
* Lots of changes related to framebuffer/window buffer resizing. Basically,Brian Paul2002-03-1610-136/+120
| | | | | | | instead of passing a GLcontext* to ResizeBuffers(), pass a GLframebuffer*. The idea is that a window can be resized without it being bound to a rendering context. This makes for a nice clean-up in the XFree86 server-side GLX code. Renamed ctx->Driver.ResizeBuffersMESA() to ctx->Driver.ResizeBuffers().
* fixed pointer arithmetic error in glCopyPixelsBrian Paul2002-03-141-3/+3
|
* new assertions, use INLINE macro (Klaus Niederkrueger)Brian Paul2002-03-081-25/+46
|
* silence gcc warnings (Marc La France)Brian Paul2002-03-011-14/+15
|
* Updated 1D/3D/cube mipmapping code to work like the new 2D code.Brian Paul2002-02-171-425/+459
|
* Simplified fog code.Brian Paul2002-02-174-215/+98
|
* don't include s_fog.hBrian Paul2002-02-173-6/+3
|
* Lots of improvements in the 2D texture sampling code. Fewer function callsBrian Paul2002-02-171-112/+315
| | | | | and no more switches inside loops. To do: give the 1D/3D/cube routines the same treatment.
* Optimized the interpolate_texcoords() function:Brian Paul2002-02-171-38/+148
| | | | | Use fast approximation to log(). Check for dq==0 to avoid a per-pixel divide.
* removed dead codeBrian Paul2002-02-161-18/+7
|
* Finished up GL_ARB_depth_texture and GL_ARB_shadow.Brian Paul2002-02-151-338/+359

|
* added an assertion, fix typoBrian Paul2002-02-061-3/+7
|
* fixed typo in depth_test_pixels(), should fix reported VTK failuresBrian Paul2002-02-061-2/+2
|
* Clean-up and remove dead code related to depth/stecil testing.Brian Paul2002-02-044-203/+153
|
* Converted line drawing over to new span code, pb no longer used.Brian Paul2002-02-0221-1241/+585
| | | | | Big clean-up of line drawing code. Removed many obsolete span processing functions.
* sw_span can now hold x/y arrays of fragment positions - getting ready toBrian Paul2002-02-0223-599/+794
| | | | | ditch the pb (pixel buffer) code. Converted point drawing, bitmaps and aa lines to use new span functions.
* Clean-up and optimize alpha test code.Brian Paul2002-01-317-557/+463
| | | | Major clean-up of pixel zoom code.
* don't use affine/persp_textured_triangle funcs when CHAN_BITS > 8Brian Paul2002-01-301-3/+3
|
* Still more texture/span simplification and clean-up.Brian Paul2002-01-288-172/+85
| | | | Updated comments, fixed indentation, etc.
* More span improvements. Removed _mesa_write_monocolor_span().Brian Paul2002-01-289-355/+159
| | | | | Removed last of span.filled* flags and Klaus's macros. More simplification of triangle functions.
* More span clean-up, mostly texture-related.Brian Paul2002-01-2813-981/+249
| | | | | _mesa_rasterize_span() is gone, replaced by new _mesa_write_textured_span(). Removed some unneeded triangle functions - more simplification possible.
* LOTS of changes, building upon Klaus's work.Brian Paul2002-01-2718-1437/+1095
| | | | | struct sw_span is used throughout span/fragment processing. This is leading to less code and more chances for optimization.
