A Radiative Transfer Framework for Rendering Materials with Anisotropic Structure

Wenzel Alban Jakob

The radiative transfer framework that underlies all current rendering of volumes is limited to scattering media whose properties are invariant to rotation. Many systems allow for "anisotropic scattering," in the sense that scattered intensity depends on th ...

Efficient volume rendering on the body centered cubic lattice using box splines

Dimitri Nestor Alice Van De Ville

We demonstrate that non-separable box splines deployed on body centered cubic lattices (BCC) are suitable for fast evaluation on present graphics hardware. Therefore, we develop the linear and quintic box splines using a piecewise polynomial (pp)-form as o ...

ESM-Blur: Handling and Rendering Blur in 3D Tracking and Augmentation

Vincent Lepetit

The contribution of this paper is two-fold. First, we show how to extend the ESM algorithm to handle motion blur in 3D object track- ing. ESM is a powerful algorithm for template matching-based tracking, but it can fail under motion blur. We introduce an i ...

Improving the Believability of Virtual Characters Using Qualitative Gesture Analysis

Ronan Boulic, Manuel Peinado

This paper describes preliminary results of a research performed in the framework of the Enactive project (EU IST NoE Enactive). The aim of this research is to improve believability of a virtual character using qualitative analysis of gesture. Using techni ...

seeCell: Visualization and Tracking Dedicated to Cell Analysis

Melody Swartz, Robin Mange

This paper presents a method for the real-time tracking and rendering of dendritic cells in a stream of microscopes images, as implemented in the software seeCell (TM) developed by Visualbiotech (Mange, 2008). The main guideline is how computer graphics te ...

Visualization and analysis of SPH data

Pierre Maruzewski

Advances in graphics hardware in recent years have led not only to a huge growth in the speed at which 3D data can be rendered, but also to a marked change in the way in which different data types can be displayed. In particular, point based rendering tech ...

Multiple-View Scenes: Reconstruction and Virtual Views

Michel Bierlaire, Jean-Philippe Thiran, Javier Cruz Mota

The problem of generating a virtual view of a scene, i.e. a view from a point where there is not a physical camera to capture the scene, has received recently a lot of attention from the computer vision community. This is probably due to the increase of th ...

A Computer-Based Real-Time Simulation of Interventional Radiology

Hannes Bleuler, Lindo Robert Duratti, Fei Wang, Evren Samur

Interventional radiology is a minimally invasive procedure where thin instruments, guidewires and catheters or stents are steered through the patient’s vascular system under X- ray imaging for treatment of vascular diseases. The complexity of these procedu ...

Tone Mapping For High Dynamic Range Displays

Sabine Süsstrunk, Laurence Meylan

We address the problem of re-rendering images to high dynamic range (HDR) displays, which were originally tone-mapped to standard displays. As these new HDR displays have a much larger dynamic range than standard displays, an image rendered to standard mon ...
