Hi Taff ... One way of doing this is to divide the surface into concentric bands and then place one circle on each of these bands. Each circle is rotated a...

Hi Roger ... The overlaps would need to be processed after triangulation. When you had a set of coplanar triangles you would need to find the overlaps between...
