Principal component and Voronoi skeleton alternatives for curve reconstruction from noisy point sets 

Ruíz, Óscar; Vanegas, Carlos; Cadavid, Carlos (Taylor & Francis, 2007-10)
Surface reconstruction from noisy point samples must take into consideration the stochastic nature of the sample -- In other words, geometric algorithms reconstructing the surface or curve should not insist in following ...

Geodesic-based manifold learning for parameterization of triangular meshes 

Acosta, Diego A.; Ruíz, Óscar E.; Arroyave, Santiago; Ebratt, Roberto; Cadavid, Carlos; Londono, Juan J. (Springer Verlag, 2014)
Reverse Engineering (RE) requires representing with free forms (NURBS, Spline, Bézier) a real surface which has been pointsampled -- To serve this purpose, we have implemented an algorithm that minimizes the accumulated ...

Gabriel-constrained Parametric Surface Triangulation 

Ruíz, Óscar E.; Cadavid, Carlos; Lalinde, Juan G.; Serrano, Ricardo; Peris-Fajarnés, Guillermo (2008-10)
The Boundary Representation of a 3D manifold contains FACES (connected subsets of a parametric surface S : R2−R3) -- In many science and engineering applications it is cumbersome and algebraically difficult to deal with ...

Spectral-based vertex re-labeling for mesh segmentation 

Mejía, Daniel; Ruíz, Óscar E.; Cadavid, Carlos (2015)
Mesh segmentation can be achieved by considering (a) geometric, (b) topologic or (c) a combination of geometric and topologic features on the surface Altough considering geometric characteristics would be relatively easy, ...
