If I have two triangles in three dimensions with vertices a1,b1,c1 and a2,b2,c2, and want to overlay them such that the distance between corresponding verticies is minimized, i.e. such that the total distance between the sum of the distances between the vertices a1-a2, b1-b2 and c1-c2 are minimized, is there a way to do this other than least-squares? I need a fast method as I'm going to be doing this thousands of times in a program but I can't think of a solution that works.(adsbygoogle = window.adsbygoogle || []).push({});
