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 ...
Ray-Casted BlockMaps for Large Urban Models Visualization
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We introduce a GPU-friendly technique that efficiently exploits the highly structured nature of urban environments to ensure rendering quality and interactive performance of city exploration tasks. Central to our approach ...
QuadCover - Surface Parameterization using Branched Coverings
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We introduce an algorithm for the automatic computation of global parameterizations on arbitrary simplicial 2-manifolds, whose parameter lines are guided by a given frame field, for example, by principal curvature frames. ...
Highly Parallel Fast KD-tree Construction for Interactive Ray Tracing of Dynamic Scenes
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We present a highly parallel, linearly scalable technique of kd-tree construction for ray tracing of dynamic geometry. We use conventional kd-tree compatible with the high performing algorithms such as MLRTA or frustum ...
Adaptive Space Deformations Based on Rigid Cells
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We propose a new adaptive space deformation method for interactive shape modeling. A novel energy formulation based on elastically coupled volumetric cells yields intuitive detail preservation even under large deformations. ...
Geodesic-Controlled Developable Surfaces for Modeling Paper Bending
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We present a novel and effective method for modeling a developable surface to simulate paper bending in interactive and animation applications. The method exploits the representation of a developable surface as the envelope ...
Real-Time Simulation of Thin Shells
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
This paper proposes a real-time simulation technique for thin shells undergoing large deformation. Shells are thin objects such as leaves and papers that can be abstracted as 2D structures. Development of a satisfactory ...
Global Illumination using Photon Ray Splatting
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We present a novel framework for efficiently computing the indirect illumination in diffuse and moderately glossy scenes using density estimation techniques. Many existing global illumination approaches either quickly ...
Markerless 4 gestures 6 DOF real-time visual tracking of the human hand with automatic initialization
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
In this paper we present a novel computer vision based hand-tracking technique, which is capable of robustly tracking 6+4DOF of the human hand in real-time (at least 25 frames per second) with the help of 3 (or more) ...
