I am so happy that our project is on the right track.
We have managed to implement the final function (poly2fv) on time.
This function perform Constrained Delaunay triangulation that i useful for plotting polygons with inner holes.
The function is implemented as a cc source file ,and it uses the polytri library which can be found here:
We have also adapted some of the ClipperLib Benchmarks to Octave and here is a screenshot for one of them:
