* indices: fix provoking vertex for quads/quadstripsIlia Mirkin2015-04-181-3/+10
| | | | | | | | | | This allows drivers to provide consistent flat shading for quads. Otherwise a driver that only supported tris would have to force last provoking vertex when drawing quads (and would have to say that quads don't follow the provoking vertex convention).

* primconvert: select pv convention only from flatshade_firstIlia Mirkin2015-04-181-2/+1
| | | | | | | | | This should match to how drivers program hardware. flatshade relates to whether color inputs are interpolated, not the provoking vertex convention. Signed-off-by: Ilia Mirkin <[email protected]> Reviewed-by: Rob Clark <[email protected]>
* u_primconvert: add primitive restart supportDave Airlie2015-03-206-86/+201
| | | | | | | | | | | | | | | | | | | | This add primitive restart support to the prim conversion. This involves changing the API for the translate functions as we need to pass the prim restart index and the original number of indices into the translate functions. primitive restart is support for quads, quad strips and polygons. This deal with the case where the actual number of output primitives is less than the initially calculated number, by filling the rest of the output primitives with the restart index, the other option is to reduce the output prim number, but that will make the generator code a bit messier.

* gallium/auxiliary/indices: fix start paramMarc-Andre Lureau2015-03-041-4/+4
| | | | | | | | | | | Since commit 28f3f8d, indices generator take a start parameter. However, some index values have been left to start at 0. This fixes the glean/fbo test with the virgl driver, and copytexsubimage with freedreno. Reviewed-by: Ilia Mirkin <[email protected]> Cc: "10.4 10.5" <[email protected]>

* u_primconvert: Copy min/max_index from the original primitive.Eric Anholt2014-08-081-4/+2
| | | | | | | | | | | | | | | | | | These values are supposed to be the minimum/maximum index values used to read from the vertex buffers. This code either copies index values out of the old IB (so, same min/max as the original draw call), or generates a new IB (using index values between the start and the start + count of the old array draw info, which just happens to be what min/max_index are set to by st_draw.c). We were incorrectly setting the max_index in the converting-from-glDrawArrays case to the start vertex plus the number of vertices generated in the new IB, which broke QUADS primitive conversion on VC4 (where max_index really has to be correct, or the kernel might reject your draw call due to buffer overflow).

* indices: add translate/generate functions for unfilled modesKeith Whitwell2009-03-046-1/+1622
| | | | | | | | | | | | Most of the time unfilled rendering requires a lot more thought than just translating triangles to lines or points. But sometimes, you can do exactly that, and it can be quite a bit quicker. Add code to do the translation. The caller has to determine whether it's a legal thing to do in the current state, in particular you'd need: - culling disabled - offset disabled - same front and back fill modes - possibly other stuff I can't think of.

* gallium: add new aux lib for index list translationsKeith Whitwell2009-02-057-0/+5859
Could this be the ultimate index list translating utility? Maybe, but it doesn't yet include support for splitting primitives. Unlike previous attempts, this captures all possible combinations of API and hardware provoking vertex, supports generated list reuse and various other tricks. Relies on python-generated code.
