An Interdisciplinary VR-Architecture for 3D Chatting with Non-verbal Communication

Daniel Thalmann, Stéphane Gobron, Junghyun Ahn, Quentin Silvestre

The communication between avatar and agent has already been treated from different but specialized perspectives. In contrast, this paper gives a balanced view of every key architectural aspect: from text analysis to computer graphics, the chatting system a ...

Photo-Realistic Real-time Face Rendering

Daniel Chappuis

Face rendering is a really important topic in Computer Graphics because a lot of virtual simulations or video games contain virtual humans. In order to obtain a realistic face, we need to take care of skin rendering. Nowadays, we can use modern 3D scanning ...

An optimal first-order solver for the TV-$L_1$ optical flow problem

Pierre Vandergheynst, Gilles Puy, Emmanuel D'Angelo

In this study, we address the problem of computing efficiently a dense optical flow between two images under a total variation (TV) regularization and an

Real-time textured volume reconstruction using virtual and real video cameras

Daniel Thalmann, Stéphane Gobron, Junghyun Ahn, Clément Marx

Reconstructing objects in three dimensions (3D) has always been one of the primary tasks in the domain of computer graphics (CG). Succeeding in this task in real-time, including texture reconstruction, and with very low-cost hardware is the challenge prese ...

Efficient Approximate Scaling of Spherical Functions in the Fourier Domain With Generalization to Hyperspheres

Ivan Dokmanic

We propose a simple model for approximate scaling of spherical functions in the Fourier domain. The proposed scaling model is analogous to the scaling property of the classical Euclidean Fourier transform. Spherical scaling is used for example in spherical ...

Mental vision

Achille Peternier

Despite the wide amount of computer graphics frameworks and solutions available for virtual reality, it is still difficult to find a perfect one fitting at the same time the many constraints of research and educational contexts. Advanced functionalities an ...

Real-time motion planning, navigation, and behavior for large crowds of virtual humans

Barbara Yersin

Simulating crowds in real time is a challenging problem that touches many different aspects of Computer Graphics: rendering, animation, path planning, behavior, etc. Our work has mainly focused on two particular aspects of real-time crowds: motion planning ...

Fast collision detection methods for joint surfaces

Daniel Thalmann, Ronan Boulic, Ehsan Arbabi

In the recent years medical diagnosis and surgery planning often require the precise evaluation of joint movements. This has led to exploit reconstructed three-dimensional models of the joint tissues obtained from CT or MR Images (for bones, cartilages, et ...

Contact modeling and collision detection in human joints

Ehsan Arbabi

Collision detection among virtual objects is one of the main concerns in virtual reality and computer graphics. Usually the methods developed for collision detection are for either very general cases or very specific applications. The first main goal of th ...
