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.

// Exact geodesic algorithm for triangular mesh with the implementation from https://code.google.com/archive/p/geodesic/,
|
|
// and the algorithm first described by Mitchell, Mount and Papadimitriou in 1987
|
|
//
|
|
// Inputs:
|
|
// V #V by 3 list of 3D vertex positions
|
|
// F #F by 3 list of mesh faces
|
|
// VS #VS by 1 vector specifying indices of source vertices
|
|
// FS #FS by 1 vector specifying indices of source faces
|
|
// VT #VT by 1 vector specifying indices of target vertices
|
|
// FT #FT by 1 vector specifying indices of target faces
|
|
// Output:
|
|
// D #VT+#FT by 1 vector of geodesic distances of each target w.r.t. the nearest one in the source set
|
|
//
|
|
// Note:
|
|
// Specifying a face as target/source means its center.
