--- Comment #29 from Stefan D?singer <stefandoesinger at gmx.at> --- Hmm, this seems like an idea worth thinking about. The D3D behavior the proposed extension addresses is part of the D3DDECLUSAGE_POSITIONT / D3DFVF_XYZRHW vertex input semantics. For now I'm opposed to making this a vertex shader control though. The point of POSITIONT / XYZRHW is to skip vertex processing altogether, so handling POSITIONT semantics in a shader seems a bit off. Furthermore, the clipping behavior of POSITIONT depends on the depth test, so this needs a separate control anyway (or replicating the depth test interaction, which seems somewhat ugly to me because its done by a different stage in the rendering pipeline). -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
