constructive solid geometry seems good, but boundary representation looks better. I've found some resources: - an online course on Geometric Modelling http://people.bath.ac.uk/ensab/G_mod/FYGM/ http://people.bath.ac.uk/ensab/G_mod/FYGM/ - a book about boundary representation http://www.amazon.com/Boundary-Representation-Modelling-Techniques-Anthony/dp/1846283124 http://www.amazon.com/Boundary-Representation-Modelling-Tech... I think these will suffice to start. Thanks for the comments!
