Insertion temps réel d'un animateur dans un monde virtuel

The calculation of radiant energy balance in complex scenes has been made possible by hierarchical radiosity methods based on clustering mechanisms. Although clustering offers an elegant theoretical solution by reducing the asymptotic complexity of the algorithm, its practical use raises many difficulties, and may result in image artifacts or unexpected behavior. This paper proposes a detailed ...

ATLAS : planification multi-satellite dynamique en temps réel

Mission planning for a constellation of satellites is a complex problem raising significant technological challenges for tomorrow’s space systems. The large numbers of customers requests and their dynamic introduction result in a huge combinatorial search space. Today’s techniques have several limitations, in particular, it is impossible to dynamically adapt the plan during its construction, an...
