Re: [Meshlab-devel] texture coords repeated

[skunkwerk <sku...@gm...>]

is there any way to get the position (index) of a face in the m.faces vector
without an iterator?
I am asking because the way i'm testing for repeated uv coords relies on
testing adjacent faces, with the adjacent face declared like:
CFaceO* adj = fit->FFp(y); //where fit is an iterator for the current face

and if the test for identical uv coords between the current face and an
adjacent face is true, i'd like to know what the position of that adjacent
face is in the m.faces vector so I can copy it's uv coord index that i've
stored in a temporary data structure.

thanks,
imran
