A virtual reality installation

This article presents a virtual reality installation similar to a CAVE based system but less expensive and easily transportable. Like any virtual reality system else, our installation aims to immerse a user in a virtual environment. Hence, we especially focus on the userpsilas feeling of presence which means the user should be able to feel the presence of the virtual objects and his self-presence in the virtual environment. Thus, the installation must conform to the next four conditions: an immersive environment, interactions, to keep the coherence between the perception of the virtual world and the interactions and to propose an experience which generates emotions.

Real-Time Global Illumination for Games using Topological Information

Indirect Illumination is a key element to achieve realistic rendering. Unfortunately, since computing this effect is costly, there are few methods that render it with real-time frame rates. In this paper we present a new method based on virtual point lights and topological information about the scene to render indirect illumination in real-time.
