Feature request: expose preprocess remeshing

[alecjacobson]

Would it be possible to expose the "preprocessing" stage that remeshes the input (collapsing small triangles etc.) to the command line user? This could be very useful in other contexts, too.

(in the meanwhile, which function does this in the code?)

[Yixin-Hu]

I don’t want to expose that, because that function simplifies input within envelop, which may introduce self-intersections. Note that it’s not a real mesh simplification, it’s just a preprocessing.

[Yixin-Hu]

It’s in class Preprocess.

[alecjacobson]

Could you point me to the function in the code so I could dig it out if I wanted? (race condition :- ) thanks.

Line 293 & 330 in Preprocess.cpp are two functions for collapsing and swapping surface edges.
