Could you say what sources you used when making csg.js?
I see that some of it looks like O'Rourke (Computation Geometry in C).
But the BSP-based booleans still remain largely a mystery to me.
I am creating CSharpCAD, a translation of JSCAD and would appreciate any point to the source books/papers you used.
We are trying to firm up they boolean algorithm especially! [I'm cooperating with the JSCAD crowd in tracking this one down.]
Thanks! [And I really appreciate the beauty of csg.js!]
