Fast implementation of depth contours using topological sweep (2001)
Kim Miller, Suneeta Ramaswami, Peter Rousseeuw, Toni Sellares, Diane Souvaine, Ileana Streinu, ...
The concept of location depth was introduced in statistics as a way to extend the univariate notion of ranking to a bivariate configuration of data points. It has been used successfully for robust...
Perspective Projections and Removal of Degeneracies (1998)
Francisco Gomez, Ferran Hurtado, Toni Sellares, Godfried Toussaint
In this paper we consider the following problems: (1) computing projections with distinct x-coordinates, (2) computing non-collinear projections, (3) computing noncocircular projections, and (4)...
An Object Oriented Approach for Teaching Visibility Computation Algorithms (1995)
Xavier Pueyo, Frederic Perez, Toni Sellares, Josep Suy
In this paper we present an approach for teaching visibility computation algorithms. Its suitability for undergraduate and graduate courses is discussed. The approach is based on the abstraction,...
