Computing Closed Skycubes
In this paper, we tackle the problem of efficient skycube computation. We introduce a novel approach significantly reducing domination tests for a given subspace and the number of...

From a Closed Piecewise Geodesic to a Constriction on a Closed Triangulated Surface
Constrictions on a surface are deļ¬ned as simple closed curves whose length is locally minimal. In particular, constrictions are periodic geodesics. We use constrictions in order...
