2007-05-22fog: fix issues with negative fog coords (may fix #10529)Roland Scheidegger
Rework tnl fog a bit. Make sure we always use ABS(eyez) when fog coord source is depth, OTOH it does not seem to be necessary to use it (as was done before in some cases) if fog coord source is fogcoord (just to save some work). This fixes tests/fog (the first 2 cases) with i915/i915tex.
2006-12-13Checkpoint work for new GLSL compiler back-end.Brian
Among changes: Remove ctx->FragmentProgram._Active Remove _UseTexEnvProgram Move _MaintainTnlProgram, _MaintainTexEnvProgram, _TexEnvProgram and _TnlProgram fields. Remove/disable old GLSL interpreter code.
2006-06-14A number of vertex buffer fields like NormalPtr, FogCoordPtr, etc are reallyBrian Paul
just aliases for members of the VB->AttribPtr[] array. Begin replacing FogCoordPtr with VB->AttribPtr[_TNL_ATTRIB_FOG], and similarly for NormalPtr, TexCoordPtr, PointSizePtr, etc.
2006-03-21GLSL fixes:Michal Krol
- generate error on NULL pointers in glShaderSourceARB; - reinstall program object, if current, in glLinkProgramARB; - vertex and fragment shaders are optional in program object; - floor asm was wrongly computed for x86 back-end; - allow for (void) idiom in function prototypes; - all fixed-state uniforms are updated; - local variable initializers are working; - implement texture* and shadow* functions for vertex processor; - generate error if too many arguments in general constructor; - trim unused data in general constructor; - struct r-value field select was badly relocated; Changes: - add derived state gl_fog_attrib::_Scale; - add derived state gl_light::_CosCutoffNeg;
2006-02-13Add ARB_vertex_shader stage just before render stage.Michal Krol
If enabled, all other stages, except render, are disabled.

2005-09-19additional wrapper updates, bug 4468Brian Paul
2005-04-22Simplify the pipeline_stage structureKeith Whitwell
- remove input/output fields, input tracking removed. - remove state fields, the validate function now called on every statechange. - add an explicit 'create' function. Add in code to build vertex program to implement current t&l state. Still disabled, but turn on with a #define in t_vp_build.h.

2004-04-23Added ctx->Vertex/FragmentProgram._Enable flags. Set when vertex/fragmentBrian Paul
program is enabled AND the currently bound program is valid. Check _Enable instead of Enable to prevent things from blowing up when someone calls glEnable(GL_VERTEX_PROGRAM_ARB) without actually defining a program.
2004-02-25use ABS(Z) when computing blend factorsBrian Paul
2004-02-17A few more tweaks to fog code.Brian Paul
Remove unneeded FABSF() macros. Added blend factor clamping in a few spots.
2004-02-17A bit of an overhaul of the fog code.Brian Paul
glFogCoord didn't always work reliably. ARB fragment program fog options work now. Per-fragment fog computations are now perspective corrected.

2002-10-24Header file clean-up:Brian Paul
1. Remove all.h and PC_HEADER junk. 2. Rolled mem.c and mem.h into imports.c and imports.h 3. Include imports.h instead of mem.h Restore _mesa_create/initialize_context() to be like they were in 4.0.4 New wrappers for a few std C functions: _mesa_atoi(), _mesa_strstr(), etc.
2002-01-22Clean-up/renaming of the per-vertex attribute bits, specifically, theBrian Paul
VERT_BIT_* flags are new and used in many places (esp in T&L code). Updated some comments for doxygen. Various code clean-ups.
2002-01-06Another vertex program checkpoint: clean-up of vertex attribute storageBrian Paul
in vertex_buffer. Improved vertex program pipeline stage such that output registers can be processed in a loop. Getting closer to where we need to be in order to implement performance optimizations...
2002-01-05Vertex program checkpoint commit: converted all vertex attributes (color,Brian Paul
normal, texcoords, fogcoord, secondary color, etc) to GLfloat[4] datatype. Aliasing of glVertex, glNormal, glColor, glFogCoord, etc. to glVertexAttrib now complete.
2001-12-18Replace old matrix stacks with new code based on struct matrix_stack.Brian Paul
Moved vertex program hash table into shared context state. Implemented reference counting for vertex programs. Replaced tnl "ProjectedClip" with "Ndc" (normalized device coordinates).
