OpenSCAD has two ways to create shapes, one is the commonly used primary
shape modules like cube(), cylinder(), etc. The other is polyhedron in which
you can define points of your choice. 

It's true that OpenSCAD doesn't calc something like intersection using the
primary shapes modules, but you can always achieve this with polyhedron. In
my code, I'm doing the intersection all the time, line-line, line-plane,
plane-plane ... etc. I believe it's won't be that difficult to find
intersection of object.
