2007-07-26don't use rgba_line() if CHAN_BITS==32Brian
2007-07-21Remove ctx->Point._Size and ctx->Line._Width.Brian
The clamping for these values depends on whether we're drawing AA or non-AA points, lines. Defer clamping until drawing time. Drivers could compute and keep clamped AA and clamped non-AA values if desired.
2007-05-20Overhaul/simplify SWvertex and SWspan attribute handling.Brian
Instead of separate fog/specular/texcoord/varying code, just treat all of them as generic attributes. Simplifies the point/line/triangle functions.
2007-04-24trim down the number of line drawing functions, special casesBrian
2007-01-24fix varying interpolationBrian
2006-10-01New SWspan and SWspanarrays typedefs.Brian Paul
2005-11-05remove unneeded #includeBrian Paul
2005-10-31check swrast->_FogEnabled instead of ctx->Fog.EnabledBrian Paul
2004-12-29use clamped Line._Width in calculationsKeith Whitwell
2004-12-18Consolidate _swrast_write_texture_span() into _swrast_write_rgba_span().Brian Paul
2004-11-27Change the dispatch offsets for the VertexAttrib*NV functions so they don'tBrian Paul
alias with the corresponding ARB functions. GL_ARB_vertex_shader (and OpenGL 2.0's) VertexAttrib functions don't alias with conventional vertex attributes, as GL_NV_vertex_program does. So, the ARB and NV version of VertexAttrib need to be distinct.
2003-12-09Update NEED_SECONDARY_COLOR macro to test if either vertex/fragmentBrian Paul
programs are enabled and if they need secondary color input register. Patch by Karl Rasche, with tweaks by Brian.
2003-09-18Move away from using the ctx->_TriangleCaps bitfield.Brian Paul
New macros in context.h for testing state: NEED_SECONDARY_COLOR and NEED_TWO_SIDED_LIGHTING.
2003-08-30Silence compiler warnings about implicit casts or conversions by supplying ↵Karl Schultz
explicit casts and/or tweaking constant and variable definitions.
2003-04-08Added ctx->Texture._EnabledCoordUnits bitfield.Brian Paul
Fixed some vertex array / vertex program glitches with glDrawElements. Fixed some fragment program runtime bugs. Non-trivial Cg programs are running now.
2003-03-25replace _mesa_ prefix with _swrast_, remove s_histogram.[ch]Brian Paul
2003-03-01Killed mmath.[ch]. Moved low-level functions/assembly code into imports.[ch]Brian Paul
Moved type conversion and interpolation macros into macros.h Updated all the files that used to include mmath.h
2003-01-20fix an assertionBrian Paul
2002-11-14Overhaul of line drawing template code. Make better use of sw_span mechanism.Brian Paul
2002-10-30s/printf/_mesa_printf/Brian Paul
2002-08-07struct sw_span is again allocated on the stack, but the arrays of spanBrian Paul
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.
2002-06-15Implemented GL_NV_texture_rectangle extension.Brian Paul
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.
2002-04-19Allocate a sw_span struct in the swrast context instead of allocating itBrian Paul
on the stack frame in the point/line/triangle functions. (Klaus Niederkrueger) This should solve the performance problem Karl found on Windows.
2002-04-19casts to fix GLint/GLuint mismatchesBrian Paul
2002-04-12Klaus Niederkrueger's latest changes: use INIT_SPAN() to init span primitiveBrian Paul
type, width, interp mask and array mask.
2002-02-15added SPAN_SPEC flag in smooth_multitextured_line()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.
2002-01-16changed PB (pixel buffer) to use texcoord[4] arrayBrian Paul
2002-01-16set PB->haveSpec in line functions that emit specular colorBrian Paul
2001-11-06casts to silence warnings from gcc 2.96Brian Paul
2001-08-20removed a semicolon in the USE() macroBrian Paul
2001-08-20new debugging codeBrian Paul
2001-06-11check for PB overflow in general_flat_rgba_line()Brian Paul
2001-05-21fixed a number of multi-texture line bugsBrian Paul
2001-05-17Fix order of decomposition of quad.Keith Whitwell
Remove 'swrast->_MultiTexEnabled' derived value.
2001-05-03interpolate fog valus as floats, not fixed - fixed the swrast fog problemBrian Paul
2001-03-29Removed DD_Z_NEVER.Brian Paul
Replaced SEPERATE with SEPARATE. Renumbered _NEW_ flags. Removed _NEW_COLORTABLE.
2001-03-12Consistent copyright info (version number, date) across all files.Gareth Hughes
2001-03-08do fog interpolation if INTERP_FOG is defined, not when INTERP_Z is definedBrian Paul
2001-03-03lots of gl_*() to _mesa_*() namespace clean-upBrian Paul
2001-02-16Allow swrast to cope (fairly) cleanly with GL_SEPERATE_SPECULAR whenKeith Whitwell
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.
2001-01-23Replaced struct gl_visual with struct __GLcontextModesRec from glcore.h.Brian Paul
Replace "RGBAMode" with "rgbMode", etc. Other minor clean-ups.
2001-01-13Use correct pv in swrast lines routinesKeith Whitwell
2000-11-22 Modified Files:Jouk Jansen
Mesa/src/descrip.mms Mesa/src/swrast/s_lines.c VMS compile support Added some Type casts to avoid warnings ----------------------------------------------------------------------
2000-11-19Replaced Texture.CurrentD[] with separate Texture.Current1/2/3D vars.Brian Paul
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.
2000-11-16Move the transform and lighting code to two new directoriesKeith Whitwell
math: Provides basic matrix and vector functionality that might be useful to multiple software t&l implementations, and is used by core mesa to manage the Model, Project, etc matrices. tnl: The real transform & lighting code from core mesa, including everything from glVertex3f through vertex buffer handling, transformation, clipping, lighting and handoff to a driver for rasterization. The interfaces of these can be further tightened up, but the basic splitting up of state and code move is done.
2000-11-13Cleanup of derived state calculation prior to seperating software T&LKeith Whitwell
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.
2000-11-10minor changes to silence compiler warningsBrian Paul
2000-11-05hooked in new AA line code, minor clean-upBrian Paul
2000-11-05Reorganized software rasterizer as a module which manages its own state,Keith Whitwell
with tighter interfaces with the rest of the world. Proper documentation to come.
