* gallium: convert rasterizer state to use gl-style front/back conceptsKeith Whitwell2010-05-141-37/+4
| | | | | | | | | | | | Use front/back instead of cw/ccw throughout. Also, use offset_point/line/fill instead of offset_cw/ccw. Brings gallium representation of this state into line with its main user, and also what turns out to be the most common hardware representation. This fixes a long-standing bias in the interface towards the architecture of the software rasterizer.
* gallium: rework provoking vertex codeBrian Paul2010-05-051-1/+4
| | | | | | | | | | | | | | Builds on commit ddb0e18f6c5582d4d2cc59ffd16ad9c4639ed059 and fixes regressions in glean clipFlat test. We assume that Gallium drivers observe flatshade_first for all triangles and that all the assorted per-triangle calls in the 'draw' module also follow flatshade_first. Everything else builds on those rules. Gallium does not use follow flatshade_first for GL quads, quad strips and polygons; the "last" vertex is always the provoking vertex for those prims. So now there are separate QUAD_FIRST_PV and QUAD_LAST_PV macros in the draw primitive decomposition code instead of one QUAD macro.

| * softpipe: Fix division by zeroArpad Borsos2010-04-141-3/+3
| | | | | | | | | | | | | | This can be triggered by running the cairo tests using the gl backend and softpipe. Signed-off-by: Brian Paul <[email protected]>
* | softpipe: fix computation of fragment[FACE] attributeBrian Paul2010-04-181-3/+7
| | | | | | | | | | | | | | In TGSI, front facing is +1 and back-facing is -1. We were computing this attribute as +1 and 0 before. However, the value isn't actually used anywhere because we machine->Face attribute overrides it in tgsi_exec.c. That could be changed, removing some special-case code...

* softpipe: support all TGSI fragment coord conventions (v4)Luca Barbieri2010-01-291-4/+7
| | | | | | | | | | | | | | | | Changes in v4: - Rebase and modify for changes in previous patches Changes in v3: - Use positive caps instead of negative caps Changes in v2: - Now takes the fragment convention directly from the fragment shader Adds internal support for all fragment coord conventions to softpipe. This patch is not required for use with the current state trackers, but it allows softpipe to run any TGSI program and enhances performance.

| * gallium: fix the front face semanticsZack Rusin2009-07-011-15/+12
| | | | | | | | | | | | | | | | mesa allocates both frontface and pointcoord registers within the fog coordinate register, by using swizzling. to make it cleaner and easier for drivers we want each of them in its own register. so when doing compilation from the mesa IR to tgsi allocate new registers for both and add new semantics to the respective declarations.

* gallium: remove use of origin_lower_leftBrian Paul2009-03-201-11/+2
| | | | | | | | | | | | | | This was used to indicate OpenGL's lower-left origin for fragment window coordinates for polygon stipple and gl_FragCoord. Now: - fragment coordinate origin is always upper-left corner - GL polygon stipple is inverted and shifted before given to gallium - GL fragment programs that use INPUT[WPOS] are modified to use an inverted window coord which is placed in a temp register. Note: the origin_lower_left field still exists in pipe_rasterizer_state. Remove it when all the drivers, etc. no longer reference it.
