* struct sw_span is again allocated on the stack, but the arrays of spanBrian Paul2002-08-071-75/+79
| | | | | | | data are broken out into a new struct span_arrays which is allocated per-context (to avoid huge stack allocations - a problem on Windows). This lets us use span.redStep instead of span->redStep (for example) to hopefully get slightly better performance in the triangle functions.
* Allocate a sw_span struct in the swrast context instead of allocating itBrian Paul2002-04-191-76/+75
| | | | | on the stack frame in the point/line/triangle functions. (Klaus Niederkrueger) This should solve the performance problem Karl found on Windows.
* Klaus Niederkrueger's latest changes: use INIT_SPAN() to init span primitiveBrian Paul2002-04-121-9/+9
| | | | type, width, interp mask and array mask.
* New mipmap lambda calculation. Previously, trilinear filtering couldBrian Paul2002-03-161-10/+13
| | | | | result in _very_ blurry textures. Still need to do some optimization of the new code in s_span.c
* More span improvements. Removed _mesa_write_monocolor_span().Brian Paul2002-01-281-2/+1
| | | | | Removed last of span.filled* flags and Klaus's macros. More simplification of triangle functions.
* More span clean-up, mostly texture-related.Brian Paul2002-01-281-91/+39
| | | | | _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 Paul2002-01-271-70/+106
| | | | | struct sw_span is used throughout span/fragment processing. This is leading to less code and more chances for optimization.

* Remove 'pv' parameter from Line/Tri/Point funcs. The provoking vertexKeith Whitwell2001-01-051-7/+13
| | | | | | | | | | | | | | is always the last vertex parameter. Modify clipping to preserve pv colors. Modify swrast and X11 driver to expect the pv in the last vertex (was looking in the first vertex previously). Remove all handling of flatshading from swrast_setup. Allow drivers to override the unclipped render tabs in tnl_render_stage directly. (Like in 3.4). Removed fxsimplerender stage. Modified t_vb_rendertmp.h to remove the need for 'parity' arguments in RENDER_TRI macros.
* Replaced Texture.CurrentD[] with separate Texture.Current1/2/3D vars.Brian Paul2000-11-191-2/+2
| | | | | | | Completely removed the dirty texture object list. Set texObj->Complete to GL_FALSE to indicate dirty. Made point/line/triangle/quad SWvertex parameters const. Minor code clean-ups.
* Cleanup of derived state calculation prior to seperating software T&LKeith Whitwell2000-11-131-2/+2
| | | | | | | | | | | | into a new directory. Specifically the handling of changes to lighting lighting space (light in model vs. light in eye) have been revamped. Moved several derived values used only by swrast into that directory. Removed direct calls to swrast_flush() from vbrender.c -- pushed into ctx->Driver.RenderFinish. Optimized flat-shading case in swrast_setup.
* Reorganized software rasterizer as a module which manages its own state,Keith Whitwell2000-11-051-83/+76

* Moved software rasterizer functionality to new directory.Keith Whitwell2000-10-311-0/+517
