Sweeping by a moving solid

We have reduced the problem of a swept solid description to a global extremum search by a parameter of movement. It allows the user to apply arbitrary variable-shape and CSG solids as generators, arbitrary parametrized movement and self-intersections. An example of sweeping by falling cup and spoon is shown below.

Simulation of NC machining uses time-dependent set-theoretic operations with a part and a cutter in relative motion:
