* mesa: fix material inputs in ffvertex_prog.cKeith Whitwell2009-06-301-39/+15
| | | | | | Varying material inputs were not being picked up from the same slots where the VBO code is currently placing them (GENERIC0 and above). Most often they were just being ignored.
* mesa: more complete fix for transform_invarient glitchesKeith Whitwell2009-05-081-9/+7
| | | | | | Add a new flag mvp_with_dp4 in the context, and use that to switch both ffvertex.c and programopt.c vertex transformation code to either DP4 or MUL/MAD implementations.
* mesa/main: set PREFER_DP4 to match position_invarient codeKeith Whitwell2009-05-081-1/+1
| | | | | | | | This is a quick fix for z fighting in quake4 caused by the mismatch between vertex transformation here and in the position_invarient code. Full fix would be to make this driver-tunable and adjust both position_invarient and ffvertex_prog.c code to respect driver preferences.
* mesa: merge the prog_src_register::NegateBase and NegateAbs fieldsBrian Paul2009-04-141-2/+1
| | | | | | There's really no need for two negation fields. This came from the GL_NV_fragment_program extension. The new, unified Negate bitfield applies after the absolute value step.
* mesa: fix bug in GPU codegen for fixed-function two-sided lightingBrian Paul2009-03-311-2/+12
| | | | | | | | | | | | | The 'dots' register wasn't getting properly un-negated and un-swizzled after emitting the code for back-face lighting. So, if more than one light source was enabled, the specular exponent for the next light source was wrong. During execution we were evaluating pow(x, y) where y was negative instead of positive. This led to the outcome being zero or NaN. This fixes the occasional black triangles seen in isosurf when hacked to enable two-sided lighting.
* mesa: minor reformatting, whitespace changesBrian Paul2009-03-311-25/+26

* mesa: remove GL_MESA_program_debug extensionBrian Paul2009-03-071-1/+0
| | | | This was never fully fleshed out and hasn't been used.
* mesa: re-org texgen stateBrian Paul2009-02-211-4/+4
| | | | New gl_texgen struct allows quite a bit of code reduction.

| * mesa: increase max texture image units and GLSL samplers to 16Brian Paul2008-12-311-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The max texture coord units is still 8. All the fixed-function paths are still limited to 8 too. But GLSL shaders can use more samplers now. Note that some texcoord-related data structures are declared to be 16 elements in size rather than 8. This just simplifies the code in a few places; the extra elements aren't accessible to the user. These changes haven't been extensively tested yet, but sanity checking has been done. It should be possible to increase the max image units/samplers to 32 without doing anything special. Beyond that we'll need longer bitfields in a few places.

| | | | | | | | | | Dots is re-used if more than one light is enabled. Previously the negate flag of dots may affect next light.
