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.

// "Simplifying Surfaces with Color and Texture using Quadric Error Metrics".
|

// This allows V to be n-dimensional (where the extra coordiantes store

|
// texture UVs, color RGBs, etc.

|
|
// Inputs:
|
|
// V #V by n list of vertex positions. Assumes that vertices with
|
|
// infinite coordinates are "points at infinity" being used to close up
|
|
// boundary edges with faces. This allows special subspace quadrice for
|
|
// boundary edges: There should never be more than one "point at
|
|
// infinity" in a single triangle.
|
|
// F #F by 3 list of triangle indices into V
|
|
// E #E by 2 list of edge indices into V.
|
|
// EMAP #F*3 list of indices into E, mapping each directed edge to unique
|
|
// unique edge in E
|
|
// EF #E by 2 list of edge flaps, EF(e,0)=f means e=(i-->j) is the edge of
|
|
// F(f,:) opposite the vth corner, where EI(e,0)=v. Similarly EF(e,1) "
|
|
// e=(j->i)
|
|
// EI #E by 2 list of edge flap corners (see above).
|
|
// Outputs:
|
|
// quadrics #V list of quadrics, where a quadric is a tuple {A,b,c} such
|
|
// that the quadratic energy of moving this vertex to position x is
|
|
// given by x'Ax - 2b + c
