On Visual Similarity Based 3D Model Retrieval
(Blackwell Publishers, Inc and the Eurographics Association, 2003) -
Open Issues in Photo-realistic Rendering
(Blackwell Publishers, Inc and the Eurographics Association, 2003)For more than two decades Computer graphics researchers have tried to achieve photo-realism in their images as reliable as possible, mainly by simulating the physical laws of light and adding one effect after the other. ... -
Out-of-core compression and decompression of large n-dimensional scalar fields
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We present a simple method for compressing very large and regularly sampled scalar fields. Our method is particularlyattractive when the entire data set does not fit in memory and when the sampling rate is high relative ... -
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 ... -
Planned Sampling of Spatially Varying BRDFs
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Measuring reflection properties of a 3D object involves capturing images for numerous viewing and lightingdirections. We present a method to select advantageous measurement directions based on analyzing the estimationof ... -
Planning Collision-Free Reaching Motions for Interactive Object Manipulation and Grasping
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We present new techniques that use motion planning algorithms based on probabilistic roadmaps to control 22 degrees of freedom (DOFs) of human-like characters in interactive applications. Our main purpose is the automatic ... -
Precise Ink Drawing of 3D Models
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Drawings made with precise pen strokes accurately reveal the geometric forms that give subjects their characteristicshape. We present a system for non-photorealistic rendering of precise drawing strokes over dense 3Dtriangle ... -
Progressive Simplification of Tetrahedral Meshes Preserving All Isosurface Topologies
(Blackwell Publishers, Inc and the Eurographics Association, 2003)In this paper, we propose a novel technique for constructing multiple levels of a tetrahedral volume dataset whilepreserving the topologies of all isosurfaces embedded in the data. Our simplification technique has two ... -
Ray Differentials and Multiresolution Geometry Caching for Distribution Ray Tracing in Complex Scenes
(Blackwell Publishers, Inc and the Eurographics Association, 2003)When rendering only directly visible objects, ray tracing a few levels of specular reflection from large, low-curvaturesurfaces, and ray tracing shadows from point-like light sources, the accessed geometry is coherentand ... -
Real-Time Caustics
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We present a new algorithm to render caustics. The algorithm discretizes the specular surfaces into samplepoints. Each of the sample points is treated as a pinhole camera that projects an image of the incoming lightonto ... -
Realistic Animation of Fluid with Splash and Foam
(Blackwell Publishers, Inc and the Eurographics Association, 2003)In this paper we describe a method for modeling and rendering dynamic behavior of fluids withsplashes and foam. A particle system is built into a fluid simulation system to represent an ocean wavecresting and spraying over ... -
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 ... -
Rendering and Affect
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Previous studies at the intersection between rendering and psychology have concentrated on issues such as realismand acuity. Although such results have been useful in informing development of realistic rendering ... -
A Scalable Approach to Interactive Global Illumination
(Blackwell Publishers, Inc and the Eurographics Association, 2003)The addition of global illumination can dramatically increase the realism achievable when rendering virtual environments.In particular with interactive applications we expect the environment to reflect changes in the ... -
Shadow Volumes on Programmable Graphics Hardware
(Blackwell Publishers, Inc and the Eurographics Association, 2003)One of the best choices for fast, high quality shadows is the shadow volume algorithm. However, for real timeapplications the extraction of silhouette edges can significantly burden the CPU, especially with highly ... -
ShieldTester: Cell-to-Cell Visibility Test for Surface Occluders
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We present a novel Cell-To-Cell Visibility (C2CV) algorithm, which given two polyhedra, AandBand a connectedand oriented manifold triangle mesh, S offers a simple, fast and conservative test for detecting when A and B ... -
Solving Geometric Optimization Problems using Graphics Hardware
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We show how to use graphics hardware for tackling optimization problems arising in the field of computationalgeometry. We exemplarily discuss three problems, where combinatorial algorithms are inefficient or hard to ... -
The Stringed Haptic Workbench: a New Haptic Workbench Solution
(Blackwell Publishers, Inc and the Eurographics Association, 2003)The workbench is an interesting semi-immersive configuration for interactive tasks. However, haptic feedback, i.e.force and tactile feedback, is one important cue which is missing. To the authors' knowledge, the sole ... -
Sub-Voxel Topology Control for Level-Set Surfaces
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Active contour models are an efficient, accurate, and robust tool for the segmentation of 2D and 3D image data.In particular, geometric deformable models (GDM) that represent an active contour as the level set of an ...
