Fixing dep build script on Windows and removing some warnings. Use bundled igl by default. Not building with the dependency scripts if not explicitly stated. This way, it will stay in Fix the libigl patch to include C source files in header only mode.

// REMOVE_DUPLICATE_VERTICES Remove duplicate vertices upto a uniqueness
|
|
// tolerance (epsilon)
|
|
//
|
|
// Inputs:
|
|
// V #V by dim list of vertex positions
|
|
// epsilon uniqueness tolerance (significant digit), can probably think of
|
|
// this as a tolerance on L1 distance
|
|
// Outputs:
|
|
// SV #SV by dim new list of vertex positions
|
|
// SVI #V by 1 list of indices so SV = V(SVI,:)
|
|
// SVJ #SV by 1 list of indices so V = SV(SVJ,:)
|
|
//
|
|
// Example:
|
|
// % Mesh in (V,F)
|
|
// [SV,SVI,SVJ] = remove_duplicate_vertices(V,1e-7);
|
|
// % remap faces
|

// SF = SVJ(F);
