SwingWrapper: Retiling triangle meshes for better edgebreaker compression
Bianca Falcidieno, Jarek Rossignac, Marco Attene, Michela Spagnuolo
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, Cláudio T. Silva, Marc Alexa, Daniel Cohen-Or
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
Paul Burchard, Tolga Tasdizen, Stanley Osher, Ross Whitaker
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...
