NettetYour next choice is to use an alpha shape. In either of the above cases, the outer boundary is a triangulation. So now the problem reduces to solving for the intersection of a line with a triangulated surface. This part is pretty easy. You just need to solve for the intersection of a line with a triangle, and then repeat for each triangle. Nettet10. sep. 2013 · You can then do a 2d interpolation like z_interp = interp2 (X,Y,Z,x_interp,y_interp) If this is not the case, you should try to define your own function that can calculate z based on x and y. For the line, we have x_ray = x_source + t * x_dir y_ray = y_source + t * y_dir z_ray = z_source + t * z_dir
