* GLSL fixes:Michal Krol2006-03-211-1/+1
| | | | | | | | | | | | | | | | | | - 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;
* Add ARB_vertex_shader stage just before render stage.Michal Krol2006-02-131-1/+4
| | | | If enabled, all other stages, except render, are disabled.
* fixed constant fogcoord bug (#4729)Brian Paul2005-10-101-2/+8
|
* additional wrapper updates, bug 4468Brian Paul2005-09-191-1/+1
|
* Simplify the pipeline_stage structureKeith Whitwell2005-04-221-24/+6
| | | | | | | | | | - 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.

* Added ctx->Vertex/FragmentProgram._Enable flags. Set when vertex/fragmentBrian Paul2004-04-231-1/+1
| | | | | | | 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.
* use ABS(Z) when computing blend factorsBrian Paul2004-02-251-4/+4
|
* A few more tweaks to fog code.Brian Paul2004-02-171-6/+7
| | | | | Remove unneeded FABSF() macros. Added blend factor clamping in a few spots.
* A bit of an overhaul of the fog code.Brian Paul2004-02-171-21/+37
| | | | | | glFogCoord didn't always work reliably. ARB fragment program fog options work now. Per-fragment fog computations are now perspective corrected.
* new comments, rename some stuffBrian Paul2004-02-131-6/+13
|
* added _NEW_PROGRAM to check_state flags for pipeline stages (fixes vparray ↵Brian Paul2004-01-311-1/+1

* Removed all RCS / CVS tags (Id, Header, Date, etc.) from everything.Ian Romanick2003-06-051-1/+0

* Killed mmath.[ch]. Moved low-level functions/assembly code into imports.[ch]Brian Paul2003-03-011-6/+5
| | | | | Moved type conversion and interpolation macros into macros.h Updated all the files that used to include mmath.h
* updated email addressesBrian Paul2002-10-291-2/+2
|
* Header file clean-up:Brian Paul2002-10-241-2/+2
| | | | | | | | 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.
* Clean-up/renaming of the per-vertex attribute bits, specifically, theBrian Paul2002-01-221-4/+4
| | | | | | VERT_BIT_* flags are new and used in many places (esp in T&L code). Updated some comments for doxygen. Various code clean-ups.
* Another vertex program checkpoint: clean-up of vertex attribute storageBrian Paul2002-01-061-7/+7
| | | | | | 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...
* Vertex program checkpoint commit: converted all vertex attributes (color,Brian Paul2002-01-051-20/+20
| | | | | | normal, texcoords, fogcoord, secondary color, etc) to GLfloat[4] datatype. Aliasing of glVertex, glNormal, glColor, glFogCoord, etc. to glVertexAttrib now complete.
* Replace old matrix stacks with new code based on struct matrix_stack.Brian Paul2001-12-181-2/+2
| | | | | | Moved vertex program hash table into shared context state. Implemented reference counting for vertex programs. Replaced tnl "ProjectedClip" with "Ndc" (normalized device coordinates).

New array_cache module Support 8 texture units in core mesa (now support 8 everywhere) Rework core mesa statechange operations to avoid flushing on many noop statechanges.
