(Guest Editors) Abstract Structure Preserving CAD Model Repair (2008)
Eurographics M. Alexa, J. Marks, Stephan Bischoff, Leif Kobbelt
There are two major approaches for converting a tessellated CAD model that contains inconsistencies like cracks or intersections into a manifold and closed triangle mesh. Surface oriented algorithms...
(Guest Editors) Abstract Hierarchical Penumbra Casting (2008)
Eurographics M. Alexa, J. Marks, Samuli Laine, Timo Aila
We present a novel algorithm for rendering physically-based soft shadows in complex scenes. Instead of casting shadow rays, we place both the points to be shaded and the samples of an area light...
Abstract Structure Recovery via Hybrid Variational Surface (2008)
Eurographics M. Alexa, J. Marks, Jianhua Wu, Leif Kobbelt
Aiming at robust surface structure recovery, we extend the powerful optimization technique of variational shape approximation by allowing for several different primitives to represent the geometric...
Efficient Animation of Point-Sampled Thin Shells (2008)
Eurographics M. Alexa, J. Marks, Martin Wicke, Denis Steinemann, Markus Gross
We present a novel framework for the efficient simulation and animation of discrete thin shells. Our method takes a point sampled surface as input and performs all necessary computations without...
Support Vector Machines for 3D Shape Processing (2008)
Eurographics M. Alexa, J. Marks, Florian Steinke, Bernhard Schölkopf, Volker Blanz
We propose statistical learning methods for approximating implicit surfaces and computing dense 3D deformation fields. Our approach is based on Support Vector (SV) Machines, which are state of the...

Eurographics M. Alexa, J. Marks, Pablo Diaz-gutierrez, M. Gopi, Renato Pajarola
In this paper we explore the algorithmic space in which stripification, simplification and geometric compression of triangulated 2-manifolds overlap. Edge-collapse/uncollapse based geometric...
