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