We consider here the problem of automatically producing a ``nice'' geometric representation (in $\Re^{m}$, for $m\geq 3$) of an arbitrary 3D complex, given only its combinatorial description. The geometric realization is chosen by optimizing certain aesthetic criteria, measured by certain ``energy functions.''} }
