* Fix some issues with perspective-corrected interpolation.Brian2007-09-183-6/+6
| | | | | | | | | | In mesa_to_tgsi.c, use TGSI_INTERPOLATE_PERSPECTIVE by default (to match post-transform vertex info convention). More to be done there... In sp_quad_fs.c, interpolate W in addition to Z. This fixes the divide by zero happening in perspective_interpolation() tgsi_exec.c As it was, we were only getting perspective correction of texture coords used by the TGSI_TEX instruction since it does a homogeneous divide. Other coords/varyings were incorrect.

* Combing depth and stencil objects and making them immutable.Zack Rusin2007-09-1830-384/+337
| | | | | Converting depth and stencil objects into a single state object (d3d10 like) and making it immutable.
* Fix the warning.Zack Rusin2007-09-181-1/+1
| | | | | | The const is there to enforce the immutable state of the object, which is in reality owned by the pipe so just cast away the constness.
* Make sampler an immutable state object.Zack Rusin2007-09-1818-53/+133
| | | | Switch the sample to be an immutable state object.
* Implementing a better hash, removing state_tracker dependency from the cache.Zack Rusin2007-09-1810-116/+627
| | | | | Replacing mesa's main hash with one that handles collisions, moving state_tracker related caching to the state tracker to keep cso cache independent of it. Cleanups.
* First stab at immutable state objects (create/bind/delete)Zack Rusin2007-09-1823-59/+382
| | | | | | | We want our state objects to be immutable, handled via the create/bind/delete calls instead of struct propagation. Only implementing the blend state to see how it would look like and work.
* Replace GL_TEXTURE_* tokens with PIPE_TEXTURE_*Brian2007-09-171-2/+6
| | | | Must have missed this a while back. This fixes cube mapping.
* Plug in selection/feedback code.Brian2007-09-175-9/+205
| | | | | | | Not quite finished yet. Selection/feedback are done with a private instance of the 'draw' module in the state tracker. Not quite all the draw context's state is set yet, namely vertex format info. Hold off on that for a bit...

| | | | | | | A few functions which were basically duplicated between softpipe and the i915 driver are now re-used: draw_emit_vertex_attr() draw_compute_vertex_size()

* In draw_flatshade.c use vertex_info->interp_mode[] to choose attribs/colors ↵Brian2007-08-308-57/+56
| | | | | | | to cpy. One less dependency on the TGSI_ATTRIB_x flags. This requires setting the vertex_info->interp_mode[] values in the i915 driver and passing them to draw_set_vertex_attributes().
* Fix lost edge flags problem when clipping.Brian2007-08-302-2/+16
| | | | | | In emit_poly() we need to compute header.edgeflags from the vertex edge flags. Also need to set header.det so later stages can determine front/back orientation.
* Sketch out per-vertex point size.Brian2007-08-304-4/+31
| | | | | | | The code is all in place, but mostly disabled for now: In t_vp_build.c, write the VERT_RESULT_PSIZE register In sp_state_derived.c, need to emit vertex point size if drawing points. In setup_point() use the point size from the vertex.
