* Fix point attentuation problem (bug 11042)Brian2007-05-231-4/+6
| | | | | ctx->Point._Attentuation was computed in wrong place and the VB->Eye coord Z array wasn't indexed correctly in run_point_stage().
* fog: fix potential issues with generated vp using fogRoland Scheidegger2007-05-221-8/+15
| | | | | Change the generated vertex programs (tnl/brw) to follow the same logic as the tnl fog wrt using absolute value, and sync them up a bit (untested).
* fog: fix issues with negative fog coords (may fix #10529)Roland Scheidegger2007-05-221-7/+22
| | | | | | | 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.

| | | | point size.
* Enable texture sampling for vertex programs/shaders.Brian2007-04-171-11/+47
| | | | | | | This is a bit of a hack for now because the tnl module is using the swrast module to fetch texels. The texture fetch/filter code should probably be moved into the main/ module since it doesn't really depend upon other swrast code.
* In bind_inputs() set VB->EdgeFlag to NULL if it's not needed.Brian2007-04-171-1/+4
| | | | | | Otherwise, the clip/interp code was finding VB->EdgeFlag to be non-null and reading/writing it when the memory may have been freed earlier in free_space(). This fixes several VTK segfaults/failures reported by Brad King @ Kitware.
* cleanups for t_vb_program.cRoland Scheidegger2007-04-171-13/+19
| | | | | | use VertexProgram._Current instead of VertexProgram.Current in a few more places. Only fixup fogc and psiz in case this is really a nv program (others are fine if undefined), and fix this case up so the values actually get written.

* Use generic program limits instead of NV-specific ones to init program ↵Brian2007-04-161-1/+4
| | | | | | | | | constants. Previously, this limited us to 12 temp regs for vertex programs. Many vertex shaders could exceed that. This forces us to stop using t_vb_arbprogram.c for now because of its particular register indexing scheme. Need to increase bits allocated for register indexing, etc.
* Fix in t_vp_build: Missed necessary updates sometimesNicolai Haehnle2007-04-021-1/+2
| | | | | | | | | _mesa_update_state doesn't always reset VertexProgram._Current to NULL. This caused us to skip a necessary update of the fixed function vertex program sometimes. Change the logic such that we check for updates whenever the _Current program is either NULL or the program generated by t_vp_build.

| | | | | | This got lost with glsl-compiler-1 merge, it fixes segfaults when using ATI_fragment_shader, which uses the ProgramStringNotify mechanism but doesn't have a valid program pointer.
* add parenthesis around a bit-wise AND term in _tnl_InvalidateState()Brian2007-03-271-1/+1

* Restore the UseTexEnvProgram logic.Brian2007-03-271-1/+1
| | | | | Was removed during glsl-compiler work. Still need to go back and revisit this because of the interaction with fragment shaders...

| | | | | | | | fragment program and it doesn't need FRAG_ATTRIB_COL0. Silences valgrind warnings.
| * Add the ability to generate programs that doesn't use condition codes.Brian2007-03-231-0/+4
| | | | | | | | | | | | | | ctx->Shader.EmitCondCodes determines if we use condition codes. If not, IF statement uses first operand's X component as the condition. Added OPCODE_BRK0, OPCODE_BRK1, OPCODE_CONT0, OPCODE_CONT1 to handle the common cases of conditional break/continue.
