https://bugs.freedesktop.org/show_bug.cgi?id=57875 --- Comment #16 from Henri Verbeet --- (In reply to comment #15) > I've written an extension proposal for a new mesa extension that exposes the > CLIP_DISABLE bit. The proposal is attached, please review and comment. There > are some TODOs I'm not quite sure how to deal with, see the list in "Status". > - It probably makes sense to mention "depth" in the extension name somewhere, we really only care about the near and far clipping planes. E.g. MESA_depth_clip. - Perhaps it makes more sense to write the extension in terms of ARB_depth_clamp. I.e., provide a subset of ARB_depth_clamp, that only disables depth clipping, and generates undefined results in the depth test, except for perhaps GL_ALWAYS / GL_NEVER. (Also, note that you can't really make fragment depth values undefined before / in the fragment shader, because you have interactions with e.g. texture filtering as well.) It would avoid the perhaps somewhat questionable "ARB_depth_clamp must not be supported", and you can just defer to ARB_depth_clamp for most of the issues etc. The interaction between the two extensions just becomes that if ARB_depth_clamp is also supported you get defined depth test results. -- You are receiving this mail because: You are the assignee for the bug.
