Error-resilient transmission of 3D models
Yucel Altunbasak, Ghassan Alregib, Jarek Rossignac
In this article, we propose an error-resilient transmission method for progressively compressed 3D models. The proposed method is scalable with respect to both channel bandwidth and channel packet-loss rate. We jointly design source and channel...
Quadric-based simplification in any dimension
Michael Garland, Yuan Zhou
We present a novel generalization of the quadric error metric used in surface simplification that can be used for simplifying simplicial complexes of any type embedded in Euclidean spaces of any dimension. We demonstrate that our generalized...
Image-based spatio-temporal modeling and view interpolation of dynamic events
Simon Baker, Takeo Kanade, Sundar Vedula
We present an approach for modeling and rendering a dynamic, real-world event from an arbitrary viewpoint, and at any time, using images captured from multiple video cameras. The event is modeled as a nonrigidly varying dynamic scene, captured by...
Fast multi-level adaptation for interactive autonomous characters
Parris K. Egbert, Jonathan Dinerstein
Adaptation (online learning) by autonomous virtual characters, due to interaction with a human user in a virtual environment, is a difficult and important problem in computer animation. In this article we present a novel multi-level technique for...
Texture transfer during shape transformation
Anthony Yezzi, Greg Turk, Huong Quynh Dinh
Mappings between surfaces have a variety of uses, including texture transfer, multi-way morphing, and surface analysis. Given a 4D implicit function that defines a morph between two implicit surfaces, this article presents a method of calculating a...
ABF++: fast and robust angle based flattening
Alexander Bogomyakov, Maxim Mogilnitsky, Alla Sheffer, Bruno Lévy
Conformal parameterization of mesh models has numerous applications in geometry processing. Conformality is desirable for remeshing, surface reconstruction, and many other mesh processing applications. Subject to the conformality requirement,...
Mood swings: expressive speech animation
Erika Chuang, Christoph Bregler
Motion capture-based facial animation has recently gained popularity in many applications, such as movies, video games, and human-computer interface designs. With the use of sophisticated facial motions from a human performer, animated characters are...
Statistical geometry representation for efficient transmission and rendering
Aravind Kalaiah, Amitabh Varshney
Traditional geometry representations have focused on representing the details of the geometry in a deterministic fashion. In this article we propose a statistical representation of the geometry that leverages local coherence for very large datasets....
