David Nahon was born in Paris in 1968. He studied Electrical Engineering at SUPELEC, one of the major French “Grande Ecole”, and obtained a Master of Science in “Communications and Signal Processing” from the Imperial College of Science and Technology in London, in 1991.

Following his strong interest in visual arts he began studying 3D computer graphics and esthetics at the MSc of University Paris 8 “Art and Technology of Image”, and started a Ph.D. in “Esthetics Science and Technology of Arts”.

In 1994 he entered Z-A Production as a research and development engineer and developed PERSONA, a visual programming toolbox for procedural and interactive animation in real-time, which was used for many 3D computer animation productions in Z-A.

At the same time, he got involved in the development and direction of various interactive artwork from Maurice Benayoun, using network, real-time 3D animation, VR immersive environments, interactive sound, multimedia, internet ... and became technical and R&D director of Z-A

After 8 1/2 years at Z-A, David Nahon joined Virtools as the "VR and Simulations Solutions Manager"


David Nahon est né à Paris en 1968. Ingénieur SUPELEC (Option Signaux images et formes), il obtient le Master of Science de télécommunication et du traitement du signal de l'Imperial College of Science and Technology, à Londres, en 1991.

Poursuivant son intérêt profond pour les arts visuels, il étudie le graphisme 3D à l'université de Paris 8 et obtient un D.E.A en esthétique, sciences et technologie des arts (option Art et Technologie de l'Image).

Aprés une mission d'un an au laboratoire d'imagerie médicale LIP CNRS-Paris6, il rejoint Z-A Production en 1994, comme ingénieur de recherche et développement.

Dans ce cadre, il développe PERSONA, un outil de programmation visuel destiné à l'animation 3D en temps réel, utilisé dans de nombreuses productions de Z-A.

Dans le même temps, il fut impliqué dans le développement et la direction des oeuvres interactives de Maurice Benayoun, utilisant Internet, l'animation 3D en temps réel, les environnements immersifs 3D, le son interactif et le multimédia ... et devint directeur de la R&D et directeur technique de Z-A.

Aprés 8 1/2 ans passés au service de Z-A, David Nahon rejoint Virtools en tant que "VR and SImulation Solutions Manager"

SAS Cube / SASlib / Virtools VRPack

The SAS Cube is the first French Immersive Cubic Room to run in France, and the first running on a cluster of PCs,

The SASLib is an API similar to the CAVELib, but targetted to PC clusters. It allows to write SAS Cube applications in C/C++.

The Virtools VR Pack is a complement to Virtools Dev that permits the creations of highly interactive distributed VR content with a graphical programming language (for the SAS Cube or any other VR platform)
