Gallium, however, does not use -dedicated fog acceleration, placing it entirely in the fragment shader -instead. - -The fog coordinate should be written in ``(f, 0, 0, 1)`` format. Only the first -component matters when writing from the vertex shader; the driver will ensure -that the coordinate is in this format when used as a fragment shader input. - -TGSI_SEMANTIC_PSIZE -""""""""""""""""""" - -PSIZE, or point size, is used to specify point sizes per-vertex. It should -be in ``(p, n, x, f)`` format, where ``p`` is the point size, ``n`` is the minimum -size, ``x`` is the maximum size, and ``f`` is the fade threshold. - -XXX this is arb_vp. is this what we actually do? should double-check... - -When using this semantic, be sure to set the appropriate state in the -:ref:`rasterizer` first. - -TGSI_SEMANTIC_GENERIC -""""""""""""""""""""" - -Generic semantics are nearly always used for texture coordinate attributes, -in ``(s, t, r, q)`` format. ``t`` and ``r`` may be unused for certain kinds -of lookups, and ``q`` is the level-of-detail bias for biased sampling. - -These attributes are called "generic" because they may be used for anything -else, including parameters, texture generation information, or anything that -can be stored inside a four-component vector. - -TGSI_SEMANTIC_NORMAL -"""""""""""""""""""" - -XXX no clue. - -TGSI_SEMANTIC_FACE -"""""""""""""""""" - -FACE is the facing bit, to store the facing information for the fragment -shader. ``(f, 0, 0, 1)`` is the format.
