* Overhaul of glRead/DrawBuffer() code. Now, swrast->Driver.SetBuffer()Brian Paul2002-07-091-6/+6
| | | | | indicates the read AND draw color buffer for all software rasterization. Lots of related clean-ups. See RELNOTES-4.1 for details.
* Implemented GL_NV_texture_rectangle extension.Brian Paul2002-06-151-7/+8
| | | | | | | | | Replace struct gl_texure_object's Dimension w/ Target field. Added _EnabledUnits to struct gl_texture_attrib - the _ReallyEnabled field is obsolete, but still present for now. This effectively removes the 8-texture units limit, 32 units now possible, but unlikely! New TEXTURE_1D/2D/3D/CUBE/RECT_BIT tokens for unit->_ReallyEnabled field. Updated device drivers to use ctx->Texture._EnabledUnits.
* Allocate a sw_span struct in the swrast context instead of allocating itBrian Paul2002-04-191-57/+57
| | | | | 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.
* removed a bad assertionBrian Paul2002-03-251-2/+1
|
* New mipmap lambda calculation. Previously, trilinear filtering couldBrian Paul2002-03-161-56/+15
| | | | | result in _very_ blurry textures. Still need to do some optimization of the new code in s_span.c
* sw_span can now hold x/y arrays of fragment positions - getting ready toBrian Paul2002-02-021-7/+11
| | | | | ditch the pb (pixel buffer) code. Converted point drawing, bitmaps and aa lines to use new span functions.
* 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 Paul2002-01-281-37/+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.

| | | | | | | | | | | | | 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.

|
* 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.
