* Still more texture/span simplification and clean-up.Brian Paul2002-01-281-37/+6
| | | | Updated comments, fixed indentation, etc.
* More span improvements. Removed _mesa_write_monocolor_span().Brian Paul2002-01-281-37/+9
| | | | | Removed last of span.filled* flags and Klaus's macros. More simplification of triangle functions.
* More span clean-up, mostly texture-related.Brian Paul2002-01-281-105/+16
| | | | | _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 Paul2002-01-271-14/+31
| | | | | struct sw_span is used throughout span/fragment processing. This is leading to less code and more chances for optimization.

* Allow swrast to cope (fairly) cleanly with GL_SEPERATE_SPECULAR whenKeith Whitwell2001-02-161-8/+28
| | | | | | | | | | | | | texturing is not enabled, and without requiring the two colors be added externally. As a part of this, collapsed the decomposition of quads into triangles inside swrast to be hardwired into _swrast_Quad; removed s_quads.[ch]. Removed checks on texture state from t_vb_light.c, which was previously required by swrast. Moved the t_dd_ templates to a new directory.
* added divide by zero checksBrian Paul2001-02-071-9/+9
|
* Overhaul of texture image handling.Brian Paul2001-02-061-30/+20
| | | | | | | | | | 1. gl_texture_image struct's Data pointer points to images in driver's format. 2. Added FetchTexel() function pointer to struct gl_texture_image. 3. Changed Driver Tex[Sub]Image functions, return void now. 4. Texture storage/fetch code in new texstore.c file. 5. Removed texture.[ch] - functions moved to state.c Note: FX driver updates not finished yet.
* optimized lambda computation (Klaus Niederkrueger)Brian Paul2001-01-291-10/+9
|
* Replaced struct gl_visual with struct __GLcontextModesRec from glcore.h.Brian Paul2001-01-231-3/+3
| | | | | Replace "RGBAMode" with "rgbMode", etc. Other minor clean-ups.
* Remove 'pv' parameter from Line/Tri/Point funcs. The provoking vertexKeith Whitwell2001-01-051-28/+28
| | | | | | | | | | | | | | 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.
* disabled two optimized textured triangle functions because of texcoord ↵Brian Paul2000-12-121-4/+8

* Replaced Texture.CurrentD[] with separate Texture.Current1/2/3D vars.Brian Paul2000-11-191-67/+67
| | | | | | | 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.
* Removed Driver.Color() and Driver.Index() functions.Brian Paul2000-11-141-19/+5
| | | | | | Pass color or color index directly to WriteMono*() span functions. Updated current s/w drivers accordingly. Clean-up of X gc handling in XMesa driver.
* Cleanup of derived state calculation prior to seperating software T&LKeith Whitwell2000-11-131-3/+3
| | | | | | | | | | | | 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.
