2002-03-28reset span.end to zero after rendering the spanBrian Paul
2002-03-27fixed inequality in an assertionBrian Paul
2002-03-25removed a bad assertionBrian Paul
2002-03-23Test implementation of proposed GL_EXT_shadow_funcs extension. This justBrian Paul
generalizes the R/texture comparision operators to include all eight of the depth test comparisons.
2002-03-19Use MESA_PBUFFER_ALLOC/FREE macros to allocate all framebuffer and textureBrian Paul
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.
2002-03-19fix Intel C compiler warnings (Gerk Huisma)Brian Paul
2002-03-16New mipmap lambda calculation. Previously, trilinear filtering couldBrian Paul
result in _very_ blurry textures. Still need to do some optimization of the new code in s_span.c
2002-03-16Lots of changes related to framebuffer/window buffer resizing. Basically,Brian Paul
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().
2002-03-14fixed pointer arithmetic error in glCopyPixelsBrian Paul
2002-03-08new assertions, use INLINE macro (Klaus Niederkrueger)Brian Paul
2002-03-01silence gcc warnings (Marc La France)Brian Paul
2002-02-17Updated 1D/3D/cube mipmapping code to work like the new 2D code.Brian Paul
2002-02-17Simplified fog code.Brian Paul
2002-02-17don't include s_fog.hBrian Paul
2002-02-17Lots of improvements in the 2D texture sampling code. Fewer function callsBrian Paul
and no more switches inside loops. To do: give the 1D/3D/cube routines the same treatment.
2002-02-17Optimized the interpolate_texcoords() function:Brian Paul
Use fast approximation to log(). Check for dq==0 to avoid a per-pixel divide.
2002-02-16removed dead codeBrian Paul
2002-02-15Finished up GL_ARB_depth_texture and GL_ARB_shadow.Brian Paul

2002-02-15added SPAN_SPEC flag in smooth_multitextured_line()Brian Paul
2002-02-15fixed float->int conversion. Fix conditional for 16-bit Z buffer pathBrian Paul
2002-02-14minor clean-upBrian Paul
2002-02-12fix compiler warning (windows)Karl Schultz
2002-02-06added an assertion, fix typoBrian Paul
2002-02-06fixed typo in depth_test_pixels(), should fix reported VTK failuresBrian Paul
2002-02-04Clean-up and remove dead code related to depth/stecil testing.Brian Paul
2002-02-02Converted line drawing over to new span code, pb no longer used.Brian Paul
Big clean-up of line drawing code. Removed many obsolete span processing functions.
2002-02-02sw_span can now hold x/y arrays of fragment positions - getting ready toBrian Paul
ditch the pb (pixel buffer) code. Converted point drawing, bitmaps and aa lines to use new span functions.
2002-01-31Clean-up and optimize alpha test code.Brian Paul
Major clean-up of pixel zoom code.
2002-01-30don't use affine/persp_textured_triangle funcs when CHAN_BITS > 8Brian Paul
2002-01-28Still more texture/span simplification and clean-up.Brian Paul
Updated comments, fixed indentation, etc.
2002-01-28More span improvements. Removed _mesa_write_monocolor_span().Brian Paul
Removed last of span.filled* flags and Klaus's macros. More simplification of triangle functions.
2002-01-28More span clean-up, mostly texture-related.Brian Paul
_mesa_rasterize_span() is gone, replaced by new _mesa_write_textured_span(). Removed some unneeded triangle functions - more simplification possible.
2002-01-27LOTS of changes, building upon Klaus's work.Brian Paul
struct sw_span is used throughout span/fragment processing. This is leading to less code and more chances for optimization.
