this is just as complicated as it sounds...
but to try to simplify things, look at this image:
I need the influence generation aglorithm's for both I1 and I2.
here's what I currently have:
I've been doing google searches for the bezier aglorithm,
but havn't come up with any decent results for what I need.
if any explainations are needed, I'll come back with them,
but honestly I think it's pretty self explamitory from the images...
(a sphere from a cube)
although I could figure out I2 division if I could at least get the I1 division aglorithm
