Soft Articulated Characters with Fast Contact Handling
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
Fast contact handling of soft articulated characters is a computationally challenging problem, in part due to complex interplay between skeletal and surface deformation. We present a fast, novel algorithm based on a layered ...
Skeleton-based Variational Mesh Deformations
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
In this paper, a new free-form shape deformation approach is proposed. We combine a skeleton-based mesh deformation technique with discrete differential coordinates in order to create natural-looking global shape deformations. ...
Layered Performance Animation with Correlation Maps
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
Performance has a spontaneity and aliveness that can be difficult to capture in more methodical animation processes such as keyframing. Access to performance animation has traditionally been limited to either low degree ...
Pedestrian Reactive Navigation for Crowd Simulation: a Predictive Approach
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
This paper addresses the problem of virtual pedestrian autonomous navigation for crowd simulation. It describes a method for solving interactions between pedestrians and avoiding inter-collisions. Our approach is agent-based ...
Crowds by Example
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We present an example-based crowd simulation technique. Most crowd simulation techniques assume that the behavior exhibited by each person in the crowd can be defined by a restricted set of rules. This assumption limits ...
Depth-of-Field Rendering by Pyramidal Image Processing
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We present an image-based algorithm for interactive rendering depth-of-field effects in images with depth maps. While previously published methods for interactive depth-of-field rendering suffer from various rendering ...
Texturing Internal Surfaces from a Few Cross Sections
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We introduce a new appearance-modeling paradigm for synthesizing the internal structure of a 3D model from photographs of a few cross-sections of a real object. When the internal surfaces of the 3D model are revealed as ...
Mesh Segmentation via Spectral Embedding and Contour Analysis
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We propose a mesh segmentation algorithm via recursive bisection where at each step, a sub-mesh embedded in 3D is first spectrally projected into the plane and then a contour is extracted from the planar embedding. We rely ...
Stackless KD-Tree Traversal for High Performance GPU Ray Tracing
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
Significant advances have been achieved for realtime ray tracing recently, but realtime performance for complex scenes still requires large computational resources not yet available from the CPUs in standard PCs. Incidentally, ...
A Finite Element Method on Convex Polyhedra
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We present a method for animating deformable objects using a novel finite element discretization on convex polyhedra. Our finite element approach draws upon recently introduced 3D mean value coordinates to define smooth ...
