I cut a 3D model in unity with a plane and have the 3D points on the model for cutting face and i want to create a new face for the mesh with ear clipping algorithm. Therefore i need a counterclockwise order list of points in 3D which is a difficult part.
Is it possible to get the 2D position on the plane and then use the counterclockwise sorting algorithm and ear clipping algorithm to solve the problem in 2D?
This project will be running multiple times on the GPU and therefore efficiency is important and if there are better solutions i would like to hear them.
