3D NEURAL VISION
&
3D VIRTUAL REALITY
NEW 3D SERVICES ON TELECOM NETWORKS

Software Design, Expertise & Research-development for launching new 3D services 3D on line:
- VRML standard (Virtual Reality Modelling Language) permettant de décrire et d’animer des scènes 3D sur toute plate-forme informatique (PC ou UNIX) disposant de fonctions 3D hardware. (Cf rapport fourni)
- New MPEG4 Standard

- Survey on 3D components and 3D existing cards
- Launching new 3D tools:

        - High qualty texture rendering including animated textures (AVI or MPEGx).
        - 3D Geometric level of details computation (LOD) for large data bases linked with line bandwidth.
        - Particular case of infodiffusion.

- Expertise for other CNET Research Directions for launching new 3D Services 3D: ex: Boutique Télécom:

- GEOMETRIC and TEXTURE SCALABILITY RESEARCHES:

In order to fit the visual display complexity according to the viewing distance

Pour adapter la représentation visuelle en fonction de la distance de l'observateur:

Cette technique est essentielle pour la maîtrise de la visualisation de grandes bases de données 3D

(Patrimoine, Objets d'Art, Architecture monumentaux).
