This is probably the most unusual problem you guys ever heard of, so I'll not
be surprised if there is no solution for it available with any combination
of tools in CGAL.

Remember when you had Windows 98 and the screen would freeze up with an
error shown in a dialog popup? Remember moving this dialog box around and
its canvas leaving a drawing "trail", as if it was some sort of a slug?

I'm trying to recreate exactly that effect, but with a 3d object.

Imagine you have a not-so-primitive shape, like a 3D cross, and you want to
drag it around in a 3d space, in the 3 axis, leaving a trail behind. The
final geometry ends up being this snake-like geometry based on the initial
3D cross. As if you moved a clone of the cross just a fraction of a
millimeter, made an union boolean, and repeated until you have the desired
result.

How would you do it? Considering that a boolean would take hours of
processing.
