Quote - By the way, I'd expect that with the grid screening in place, the speed of the comparison process would depend significantly on the threshold parameter. To my shame, I have to confess that I haven't tested this, but the number of vertices considered for distance calculation should be roughly proportional to the square of the threshold value. In other words, doubling the threshold should increase the time used for distance calculations by a factor of four. So one would try to  use the smallest threshold that seems safe.

Good advice!  :D

You made excellent use of the threshold variable in the screening process.  You should see the "octree" method I was using before, when I needed such screening.  :lol:  Three or four functions, a few hundred lines of code, and the actual creation of boxes, sometimes even with geometry.  :lol:
