In 1994 Grünbaum showed that, given a point set
*S*in ℝ^{3}, it is always possible to construct a polyhedron whose vertices are exactly*S*. Such a polyhedron is called a*polyhedronization*of*S*. Agarwal et al. extended this work in 2008 by showing that there always exists a polyhedronization that can be decomposed into a union of tetrahedra (*tetrahedralizable*). In the same work they introduced the notion of a*serpentine*polyhedronization for which the dual of its tetrahedralization is a chain. In this work we present a randomized algorithm running in*O*(*n*log^{6}*n*) expected time that constructs a serpentine polyhedronization that has vertices with degree at most 7, answering an open question by Agarwal et al. **Availability**:- The paper is available in PDF (290k).
