Not sure where you are heading with it.  It would seem that you could 
take any three points and generate a triangular shape from planes and 
use it to difference a sphere surface but the edges would still be 
curved and not follow a straight line between the points. ( iso_csg has 
a function for generating a triangle from three points btw which could 
be used to clip the sphere surface )  Also I have been playing with 
using complex clippings of sphere surfaces to use as hair.  Actually it 
is kind of on the back burning right now but it seemed quite fast 
rendering.  Don't know if any of that relates to your problem.
