Error-resilient transmission of 3D models
Ghassan Alregib, Yucel Altunbasak, Jarek Rossignac
Pages: 182-208
DOI: 10.1145/1061347.1061349
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
Pages: 209-239
DOI: 10.1145/1061347.1061350
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
Sundar Vedula, Simon Baker, Takeo Kanade
Pages: 240-261
DOI: 10.1145/1061347.1061351
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
Jonathan Dinerstein, Parris K. Egbert
Pages: 262-288
DOI: 10.1145/1061347.1061352
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
Huong Quynh Dinh, Anthony Yezzi, Greg Turk
Pages: 289-310
DOI: 10.1145/1061347.1061353
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
Alla Sheffer, Bruno Lévy, Maxim Mogilnitsky, Alexander Bogomyakov
Pages: 311-330
DOI: 10.1145/1061347.1061354
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
Pages: 331-347
DOI: 10.1145/1061347.1061355
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
Pages: 348-373
DOI: 10.1145/1061347.1061356
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....
