| // CDT Construct the constrained delaunay triangulation of the convex hull | |
| // of a given set of points and segments in 2D. This differs from a direct | |
| // call to triangulate because it will preprocess the input to remove | |
| // duplicates and return an adjusted segment list on the output. | |
| // | |
| // | |
| // BACKGROUND_MESH Construct a background mesh for a (messy) texture mesh with | |
| // cosntraint edges that are about to deform. | |
| // | |
| // Inputs: | |
| // V #V by 2 list of texture mesh vertices | |
| // E #E by 2 list of constraint edge indices into V | |
| // flags string of triangle flags should contain "-c" unless the | |
| // some subset of segments are known to enclose all other | |
| // points/segments. | |
| // Outputs: | |
| // WV #WV by 2 list of background mesh vertices | |
| // WF #WF by 2 list of background mesh triangle indices into WV | |
| // WE #WE by 2 list of constraint edge indices into WV (might be smaller | |
| // than E because degenerate constraints have been removed) | |
| // J #V list of indices into WF/WE for each vertex in V | |
