The subject of this paper is "automatic construction of a Polyhedron from a Single Sketch (PSS)". Published works on the PSS problem view it as an "image processing"/"computer vision" problem where emphasis is placed at analyzing the given input (sketch) using various heuristics. This paper proposes a new methodology to solve the PSS problem based on robust… (More)

An intermediate step in the construction of a polyhedron from a partial-view sketch is the derivation of a realizable wireframe sketch, i.e., a complete sketch which is guaranteed to be the projection of a polyhedron. This paper presents a robust realizability-test based on the classical " cross-section criterion " that was developed in a geometric "… (More)
