// Triangulate the interior of a polygon using CGAL

|

// Inputs:
|
|
// V #V by 2 list of 2D vertex positions
|
|
// E #E by 2 list of vertex ids forming unoriented edges of the boundary of the polygon
|
|
// H #H by 2 coordinates of points contained inside holes of the polygon

// retain_convex_hull whether to retain convex hull {true} or trim away
|
|
// all faces reachable from infinite by traversing across

|
// non-constrained edges {false}. {true → "c" flag in `triangle`}
|
|
// Outputs:
|

// V2 #V2 by 2 coordinates of the vertives of the generated triangulation

// F2 #F2 by 3 list of indices forming the faces of the generated triangulation
