@justvanrossum @timahrens @letterror As Erik wrote above re. a 4-master 2-triangle square, there are two ways of placing the triangles, so I’ve been presuming that the triangulation is explicit at the tool level and not automated based on shortest distance. I am also presuming that axes are normalised, so every two dimensional designspace is actually a square, every three dimensional designspace is actually a cube, and every four dimensional designspace is actually a mindfuck.😁
