Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Multi-Scale Simulation For Microsurgery Trainer

Etienne Burdet, Fei Wang, Zheng Li

For use in a Virtual Reality based training system for surgical micromanipulation, we have developed a fast multi- scale FEM algorithm that concentrates detail where needed while still handling global deformations. The resulting 6- to 7-fold speed up is pr ...

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 ...

Stable Real-Time Interaction Between Virtual Humans and Real Scenes

Daniel Thalmann, Pascal Fua, Vincent Lepetit, Michal Ponder

We present an augmented reality system that relies on purely passive techniques to solve the real-time registration problem. It can run on a portable PC and does not require engineering of the environment, for example by adding markers. To achieve this res ...

Emerging Web graphics standards and technologies

Daniel Thalmann, Fengping Li

Migrating computer graphics to the Web poses several problems, but with new standards and technology advances, graphics applications can balance latency and bandwidth constraints with image quality. The paper discusses Web graphics standards, distributed v ...

Immersive VR decision training: telling interactive stories featuring advanced virtual human simulation technologies

Daniel Thalmann, Bruno Herbelin, Michal Ponder, Branislav Ulicny

Based on the premise of a synergy between the interactive storytelling and VR training simulation this paper treats the main issues involved in practical realization of an immersive VR decision training system supporting possibly broad spectrum of scenario ...

Rate-distortion optimal mesh simplification for communications

Laurent Balmelli

The thesis studies the optimization of a specific type of computer graphic representation: polygon-based, textured models. More precisely, we focus on meshes having 4-8 connectivity. We study a progressive and adaptive representation for textured 4-8 meshe ...

Modeling behaviors of interactive objects for real-time virtual environments

Daniel Thalmann

Real-time 3D graphics are being extensively used to build interactive virtual environments for a number of different applications. In many situations, virtual objects are required to exhibit complex behaviors, and the use of a versatile behavioral programm ...

Building 3D anatomical scenes on the Web

Roger Hersch, Sebastian Gerlach

We propose a new service for building user-defined 3D anatomical structures on the Web. The Web server is connected to a database storing more than 1000 3D anatomical models reconstructed from the Visible Human. Users may combine existing models as well as ...

Interactive modeling of the human musculature

Daniel Thalmann, Amaury Aubel

In this paper, we extend our previous work (Proc. Computer Animation and Simulation, pp. 125-135, Aug. 2000) and propose a muscle model that is suitable for computer graphics based on physiological and anatomical considerations. Muscle motion and deformati ...

Splines and wavelets for image warping and projection

Stefan Horbelt

This thesis investigates advanced signal processing concepts and their application to geometric processing and transformations of images and volumes. In the first part, we discuss the class of transformations that project volume data onto a plane using par ...
