// running "marching triangles" on mesh, but not in any coherent order. The

|
// output mesh should be as manifold as the input.

//
|
|
// Inputs:
|
|
// V #V by dim list of mesh vertex positions
|
|
// F #F by 3 list of mesh triangle indices into V
|
|
// S #V by 1 list of scalar field
|
|
// val value of S to remesh along
|
|
// Outputs:
|
|
// U #U by dim list of mesh vertex positions #U>=#V
|
|
// G #G by 3 list of mesh triangle indices into U, #G>=#F
|
|
// SU #U list of scalar field values over new mesh
|
|
// J #G list of indices into G revealing birth triangles
|
|
// BC #U by #V sparse matrix of barycentric coordinates so that U = BC*V

// L #G list of bools whether scalar field in triangle below or above val
