Particle-Based Simulation of Fluids
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Due to our familiarity with how fluids move and interact, as well as their complexity, plausible animation of fluidsremains a challenging problem. We present a particle interaction method for simulating fluids. The ...
Volumetric cell-and-portal generation
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We present an algorithm to generate a cell-and-portal decomposition of general indoor scenes. The method is an adaptation of the 3D watershed transform, computed on a distance-to-geometry sampled field. The watershed is ...
Cloth Motion Capture
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Recent years have seen an increased interest in motion capture systems. Current systems, however, are limitedto only a few degrees of freedom, so that effectively only the motion of linked rigid bodies can be acquired. ...
Compression of 2D Vector Fields Under Guaranteed Topology Preservation
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
In this paper we introduce a new compression technique for 2D vector fields which preserves the complete topology, i.e., the critical points and the connectivity of the separatrices. As the theoretical foundation of the ...
Hierarchical Context-based Pixel Ordering
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We present a context-based scanning algorithm which reorders the input image using a hierarchical representationof the image. Our algorithm optimally orders (permutes) the leaves corresponding to the pixels, by minimizing ...
Fast Photo-Realistic Rendering of Trees in Daylight
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We propose a fast approach for photo-realistic rendering of trees under various kinds of daylight, which is particularlyuseful for the environmental assessment of landscapes. In our approach the 3D tree models are transformedto ...
Multi-scale Feature Extraction on Point-Sampled Surfaces
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We present a new technique for extracting line-type features on point-sampled geometry. Given an unstructuredpoint cloud as input, our method first applies principal component analysis on local neighborhoods toclassify ...
Reanimating Faces in Images and Video
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
This paper presents a method for photo-realistic animation that can be applied to any face shown in a single imageor a video. The technique does not require example data of the person's mouth movements, and the image to ...
Narrative Use of Sign Language by a Virtual Character for the Hearing Impaired
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
This paper describes the concept and control of a 3d virtual character system with facial expressions and gesturesas a conversational user interface with narrative expressiveness for the hearing impaired. The gestures and ...
Visyllable Based Speech Animation
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Visemes are visual counterpart of phonemes. Traditionally, the speech animation of 3D synthetic faces involvesextraction of visemes from input speech followed by the application of co-articulation rules to generate ...
