With the new Blender Python API, do you think it would be possible to implement projective geometry? I would like to project a spline onto a mesh and create a spline from that projection. I have referred to this site as an example in some of my other posts, but this is what I would like to do in Blender: http://www.rainnea.com/cnc_toolkit.htm I will code it if I can. I just need help on some of the hurdles. I am currently looking into a geometric algebra, or Clifford algebra method of doing so.
