As discussed on irc, and for posterity: 00:35 < marcheu> you have a 16 or 8 (with multitexture) vertex cache 00:35 < marcheu> these number you see (0xFEDCBA) are not magic 00:35 < marcheu> these are the index of the vertices we want to emit 00:36 < marcheu> so FEDCBA emits vertices 15,14,13,12,11 and 10 00:36 < marcheu> but that means you have to actually place data at these locations 00:37 < marcheu> which means that if you want to do a single-pass emission you have to place the first vertex at spot 10 00:37 < marcheu> so basically the layout of the nv4 3D object is like that: 00:37 < marcheu> - vertex 0 00:37 < marcheu> - vertex 1 00:37 < marcheu> ... 00:37 < marcheu> - vertex 15 00:38 < marcheu> - vertex indices that we want fired 00:38 < marcheu> so if you want to do a 1-swoop submission, you have to start from 10 or so 00:38 < marcheu> that also means you _place_ vertex data at the right spot. right now you place it at 0 00:39 < marcheu> also you reserve one too little places on the fifo (6 instead of 7 on line 206) 00:39 < marcheu> becuase you need one spot for the FEDCBA 00:39 < marcheu> so you need 3 things: 00:39 < marcheu> - start emitting at the right place, which probably means an extra argument to BEGIN_PRIMITIVE to tell which place 00:40 < marcheu> - increase the size of the BEGIN_PRIMITIVE 00:40 < marcheu> - that was only two things :) Stephane ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
