I'm interested in CSG software that can calculate intersections between primitives with arbitrary precision (so that error does not accumulate - suppose that you wanted to use such a library to automatically generate manufacturable designs from broad geometric constraints - with current CSG libraries, you'd have to worry about precision, which would make such a program unwieldy and unreliable.)<p>I'd like to contact you directly, but I don't think hn has an IM feature.
