Scalable behaviors for crowd simulation
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Crowd simulation for virtual environments offers many challenges centered on the trade-offs between rich behavior, control and computational cost. In this paper we present a new approach to controlling the behavior of ... -
Physical Validation of Global Illumination Methods: Measurement and Error Analysis
(The Eurographics Association and Blackwell Publishing Ltd., 2004)In this paper, we present a physical validation of global illumination algorithms based on measurements from a simple experimental setup. The validation methodology emphasizes tractability and error minimization. To this ... -
Measurement-Based Interactive Simulation of Viscoelastic Solids
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Animation of viscoelastic solids in entertainment and medical applications as well as scientific simulation can be improved through observations of real world objects. This paper presents a method for simulating viscoelastic ... -
Point Cloud Collision Detection
(The Eurographics Association and Blackwell Publishing, Inc, 2004)In the past few years, many efficient rendering and surface reconstruction algorithms for point clouds have been developed. However, collision detection of point clouds has not been considered until now, although this is ... -
Cultural Heritage Preservation Using Constructive Shape Modeling
(The Eurographics Association and Blackwell Publishing Ltd., 2004)Issues of digital preservation of shapes and internal structures of historical cultural objects are discussed. An overview of existing approaches to digital preservation related to shape modeling is presented and corresponding ... -
Prototype Modeling from Sketched Silhouettes based on Convolution Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2004)This paper presents a hybrid method for creating three-dimensional shapes by sketching silhouette curves. Given a silhouette curve, we approximate its medial axis as a set of line segments, and convolve a linearly weighted ... -

Fast Hybrid Approach for Texturing Point Models
(The Eurographics Association and Blackwell Publishing Ltd., 2004)We present three methods for texturing point models from sample textures. The first method, the point parameterization method, uses a fast distortion-bounded parameterization algorithm to flatten the point model's surface ... -
Space-Time Hierarchical Radiosity with Clustering and Higher-Order Wavelets
(The Eurographics Association and Blackwell Publishing Ltd., 2004)We address in this paper the issue of computing diffuse global illumination solutions for animation sequences. The principal difficulties lie in the computational complexity of global illumination, emphasized by the movement ... -
A Viewpoint-Dependent Approach to Ray Trace Free-Form Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2004)For convincing realistic scenes objects with free-form surfaces are essential. Especially for photorealistic rendering pure polygonal models are often not sufficient. We present a new kind of algorithm to render free-form ... -

Visualizing Objects with Mirrors
(The Eurographics Association and Blackwell Publishing Ltd., 2004)We present an automatic camera and mirrors placement method for visualizing 3D scenes such that complete and nonredundant visibility is guaranteed, as well as highest image resolution. We provide algorithms and geometries ... -
Placement of Deformable Objects
(The Eurographics Association and Blackwell Publishing Ltd., 2004)With the increasing complexity of photorealistic scenes, the question of building and placing objects in three-dimensional scenes is becoming ever more difficult. While the question of placement of rigid objects has captured ... -
Real-time Rigid Body Simulation for Haptic Interactions Based on Contact Volume of Polygonal Objects
(The Eurographics Association and Blackwell Publishing, Inc, 2004)This paper proposes a new method for real-time rigid body simulations for haptic interactions based on a penalty method regarding contact volume. Analytical methods for calculation of contact forces require too much time ... -
DiFi: Fast 3D Distance Field Computation Using Graphics Hardware
(The Eurographics Association and Blackwell Publishing, Inc, 2004)We present an algorithm for fast computation of discretized 3D distance fields using graphics hardware. Given a set of primitives and a distance metric, our algorithm computes the distance field for each slice of a uniform ... -
Synthesizing Sound from Turbulent Field using Sound Textures for Interactive Fluid Simulation
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Sound is an indispensable element for the simulation of a realistic virtual environment. Therefore, there has been much recent research focused on the simulation of realistic sound effects. This paper proposes a method for ... -
