  We introduce a new way to implicitly represent swept volumes in 3D. We first
implicitize the base volume and then apply the time-dependent rigid
transformation to build an implicit representation of the swept volume. This
way, we build a fitting representation, where geometric details generated by
the rigid transformation and details of the base volume itself are both taken
into account. This representation relies on a partition of a boundary box of
the swept volume according to portions of the space related either to parts of
the base volume or to time span of the transformation.
