SwingWrapper: Retiling triangle meshes for better edgebreaker compression
Marco Attene, Bianca Falcidieno, Michela Spagnuolo, Jarek Rossignac
We focus on the lossy compression of manifold triangle meshes. Our SwingWrapper approach partitions the surface of an original mesh M into simply connected regions, called triangloids. From these, we generate a new mesh...
Progressive point set surfaces
Shachar Fleishman, Daniel Cohen-Or, Marc Alexa, Cláudio T. Silva
Progressive point set surfaces (PPSS) are a multilevel point-based surface representation. They combine the usability of multilevel scalar displacement maps (e.g., compression, filtering, geometric modeling) with the generality of point-based surface...
Geometric surface processing via normal maps
Tolga Tasdizen, Ross Whitaker, Paul Burchard, Stanley Osher
We propose that the generalization of signal and image processing to surfaces entails filtering the normals of the surface, rather than filtering the positions of points on a mesh. Using a variational strategy, penalty functions on the surface...
Motion sketching for control of rigid-body simulations
Jovan Popović, Steven M. Seitz, Michael Erdmann
Motion sketching is an approach for creating realistic rigid-body motion. In this approach, an animator sketches how objects should move and the system computes a physically plausible motion that best fits the sketch. The sketch is specified with a...
