* Fix-up tfrag/tie format mesh to a best-guess unstripped mesh with proper triangle orientation.
|
||
|
|
* The input is the tie/tfrag index list, using UINT32_MAX as primitive restart.
|
||
|
|
* The output is an unstripped index list (groups of three indices, one for each triangle)
|
||
|
|
* and a map from each element in the original index buffer to the new one.
|
||
|
|
* Ex: unstripped[old_to_new_start[i]] is the start of prim stripped_indices[i].
|
||
|
|
*
|
||
|
|
* This depends on specific behavior of the original tfrag/tie renderers, and how
|
||
|
|
* extract_tie/extract_tfrag work (basically keeping the order of vertices exactly the same as in VU
|
||
|
|
* memory).
|
||
|
|
*
|
||
|
|
* The stripping logic of shrub/merc/generic models appears to be different, and this likely won't
|
||
|
|
* work.
