Methodology for the Design of Man-Portable Power Generation Devices

Benoît Chachuat

An overview of a comprehensive methodology for the design of microfabricated fuel cell systems for portable power generation is presented. The methodology is based on a decomposition into three levels of modeling detail: (i) system-level models for process ...

Rendering massive real-time crowds

Pablo Stanislaw De Heras Ciechomski

This thesis presents how to visualize a large crowd of virtual human characters in real time on a standard issue personal computer. The virtual humans are distributed into rendering fidelities such that the humans closer to the viewer are detailed and expr ...

Efficient raytracing of deforming point-sampled surfaces

Mark Pauly

We present efficient data structures and caching schemes to accelerate ray-surface intersections for deforming point-sampled surfaces. By exploiting spatial and temporal coherence of the deformation during the animation, we are able to improve rendering pe ...

Probabilistic modeling of texture transition for fast tracking and delineation

Seyed Ali Shahrokni

In this thesis a probabilistic approach to texture boundary detection for tracking applications is presented. We have developed a novel fast algorithm for Bayesian estimation of texture transition locations from a short sequence of pixels on a scanline tha ...

Ceramic microcomponents by microstereolithography

Philippe Renaud, Heinrich Hofmann, Arnaud Bertsch, Sébastien Jiguet

This paper describes new polymer/ceramic photosensitive resins that can be used in the microstereolithography process for manufacturing complex 3D components in composite material. These new resins contain high loads (up to 80 wt.%) of alumina nanoparticle ...

Compression of 3D models with NURBS

Diego Santa Cruz Ducci

With recent progress in computing, algorithmics and telecommunications, 3D models are increasingly used in various multimedia applications. Examples include visualization, gaming, entertainment and virtual reality. In the multimedia domain 3D models have b ...

Interactive specification and extraction of free form surfaces from the visible human

Roger Hersch, Sebastian Gerlach, Laurent Saroul

We present new interaction and visualization paradigms relying on free form surfaces for studying and exploring human anatomy. We propose an interface for building three-dimensional anatomical scenes incorporating 3D anatomical organ models, freely orienta ...

Time-critical multiresolution rendering of large complex models

Very large and geometrically complex scenes, exceeding millions of polygons and hundreds of objects, arise naturally in many areas of interactive computer graphics. Time-critical rendering of such scenes requires the ability to trade visual quality with sp ...

Progressive Meshes in an Operational Rate-Distortion Sense with Application to Terrain Data

Martin Vetterli, Laurent Balmelli

This paper presents an efficient simplification method for regular meshes obtained with a binary subdivision scheme. Our mesh connectivity is constrained with a quadtree data structure. We propose a quadtree built especially for this class of meshes having ...

Progressive mesh-based coding of arbitrary-shaped video objects

Touradj Ebrahimi, Murat Kunt

While the emerging MPEG-4 standard has raised the need for efficient object-based compression, the future MPEG-7 standard motivates further research in the field of progressive, quality-scalable, and semantic representations for indexing and retrieval appl ...
