Abstract | |||||||||||||||
| Abstract. We describe a data structure for three-dimensional Nef complexes, al-gorithms for boolean operations on them, and our implementation of data structure and algorithms. Nef polyhedra were introduced by W. Nef in his seminal1978 book on polyhedra. They are the closure of half-spaces under boolean operations and can represent non-manifold situations, open and closed boundaries,and mixed dimensional complexes. Our focus lies on the generality of the data structure, the completeness of the algorithms, and the exactness and efficiency ofthe implementation. In particular, all degeneracies are handled. | |||||||||||||||
