2009-2010 CLEVER II

Collaborative Edition and Visualization Environment in Real-Time (CLEVER)

The goal of this industrial research project is to design an all-in-one collaborative visualization and editing tool, compatible with a maximum of visualization hardwares (personal computers, laptops, graphics workstations, consoles) and servers.

This study follows the previous chapter and consists in improving/complete the algorithms designed in our 3D streaming framework in order to sustain a heavy load with a restricted bandwidth.  Anti-hacking counter-measures are also investigated.

We also study different global illumination algorithms implemented on the GPU and compatible with progressive content delivery as well as ways to simulate different natural phenomenons, vegetation and cities with methods compatibles with streaming.  We also study different ways to compress efficiently the progressive delivered content and we study opportunities to generate high-frequency details with procedural algorithms implemented on the GPU.
