Coupling Terrain and Building Database Information for Ray-Tracing Applications
In this paper a methodology for the combination and integration into a single data base of terrain and building data is presented -- This study is justified if ray-tracing techniques are to be used in propagation and channel ...
DigitLAB, an Environment and Language for Manipulation of 3D Digitizations
(Presses internationales Polytechnique, 2000)
Principal component and Voronoi skeleton alternatives for curve reconstruction from noisy point sets
(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 ...
Boundary Representation of Anatomical Features
In Simulationen für Bestrahlungstherapieplanung und andere medizinischen und bioingenieur wissenschaftlichen Anwendungen hat man traditionellerweise die anatomischen Eigenschaften mittels volumenbasierten Techniken angezeigt ...
Bi-curve and multi-patch smoothing with application to the shipyard industry
Algorithms are proposed and implemented in a commercial system which allow for the C1-continuity matching between adjacent B-spline curves and B-spline patches -- These algorithms only manipulate the positions of the control ...
