Sufficiently Fat Polyhedra are not 2-castable
In this note we consider the problem of manufacturing a convex polyhedral object via casting. We consider a generalization of the sand casting process where the object is manufact...

A System for Constructing Boundary Representation Solid Models from a Two-Dimensional Sketch
This paper describes a system which converts a twodimensional sketch with hidden lines removed of a single polyhedral object into a boundary representation solid model. The system...

Polyhedral conditions for the nonexistence of the MLE for hierarchical log-linear models
We provide a polyhedral description of the conditions for the existence of the maximum likelihood estimate (MLE) for a hierarchical log-linear model. The MLE exists if and only if...

Skewed Mirror Symmetry in the 3D Reconstruction of Polyhedral Models
We aim to reconstruct three-dimensional polyhedra from axonometric line drawings. Existence of mirror symmetry in polyhedra can assist the reconstruction process. We present a new...

Reversible Polygonalization of a 3D Planar Discrete Curve: Application on Discrete Surfaces
Abstract. Reversible polyhedral modelling of discrete objects is an important issue to handle those objects. We propose a new algorithm to compute a polygonal face from a discrete ...
