Product operator on cell complexes

The intersection of extrusions is a useful tool to generatecomplex pD models starting from two or morem i D (m i p) cell complexes. This operation is particularlyuseful in the context of architectural design, wherethe 3D model of a building may be automatically generatedstarting from plan views and sections, both representedas 2D cell complexes [8].
