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.

A configuration space approach for efficient animation of human figures

Daniel Thalmann

We propose an efficient method for animation of virtual human models in an environment of obstacles. A nearby target location reachable by a human figure is given and a search is performed in the object space encompassing obstacles to obtain an optimum con ...

Low-power CMOS, analog transient-stability-simulator for a two-machine power-system

Christian Enz

This paper presents a low-power analog simulator for the transient stability of a two-machine power system. The simulator is implemented in a standard digital CMOS process. Its building blocks are: sine shaper, transconductor with extended linear range, an ...

Communication Costs of Parallel Volume Rendering of Large Images on a Network Of Workstations

Roger Hersch

Direct Volume Rendering is a popular technique for visualization of 3D datasets that offers many advantages over other algorithms but requires important computing power. Efficient parallelization is therefore an essential need. Taking advantage of an exist ...

Measurement of the optical depth at the third electron cyclotron harmonic in tore supra

Olivier Sauter, Timothy Goodman, Minh Quang Tran, Antoine Pochelon

The linear relativistic theory of electron cyclotron wave propagation predicts partial absorption of the extraordinary mode at the third electron cyclotron harmonic for typical parameters of present day tokamak plasmas. Since the waves are not totally damp ...

Rendering real-world objects without 3-D model

Roger Hersch

This paper presents a new approach to rendering arbitrary views of real-world objects of complex shapes, captured by a capturing device. We propose to represent an object by a small set of corresponding 2-D views, and to construct any other view as a combi ...

Rendering real-world objects using view interpolation

Roger Hersch

Presents a new approach to rendering arbitrary views of real-world 3D objects of complex shapes. We propose to represent an object by a sparse set of corresponding 2D views, and to construct any other view as a combination of these reference views. We show ...

An adaptive spatial subdivision of the object space for fast collision detection of animated rigid bodies

Daniel Thalmann

Collision detection tests between objects dominate run time simulation of rigid body animation. Traditionally hierarchical bounding box tests are used to minimize collision detection time. But the bounding boxes do not take shapes of the objects into accou ...

Optimally Profiling and Tracing Programs

James Richard Larus

This paper describes algorithms for inserting monitoring code to profile and trace programs. These algorithms greatly reduce the cost of measuring programs with respect to the commonly used technique of placing code in each basic block. Program profiling c ...

Efficient Program Tracing

James Richard Larus

A program trace lists the addresses of instructions executed and data referenced during a program's execution. Earlier approaches to collecting program traces, including abstract execution and optimal control tracing, are reviewed. Two tracing systems base ...

An integrated system for modeling, animating and rendering hair

Daniel Thalmann

There are basically four problems to solve in order to produce realistic animated synthetic actors with hair: hair modeling and creation, hair motion, collision detection and hair rendering. The authors describe a complete methodology to solve these basic ...
