Acting as a "technopole" which means as a high technology center for economical development, LMT (Laval Mayenne Technopole) has created a virtual reality platform called CLARTE (CLARTE's website). CLARTE, located in Laval - France, was founded to help companies to get skills on VR technologies and to develop new Virtual environments based on immersive and interactive system.
CLARTE works with two main immersive systems:
- the SASCube (a four screens cubic display)
- the Reality Centre (a 12 x 3.4 meters hemi-cylindrical screen)

The SASCube

The Reality Center
Clusters are used in such systems to share the load and get better efficiency with a lower cost than a high computer. CLARTE develops on two different clusters:
- a standard computer based cluster. This cluster is composed by Dell computers, each computer embedding a professional quadbuffer video card which enables genlocking on the whole cluster. To display on a screen we need there only one computer.
- a VR specific cluster. This ORAD cluster uses specific DVG boards to mix video singnals and produce one stereoscopy display (active or passive) with two computers. For instance in the SASCube, we need eight computers to have stereoscopy on each screen (two computers per screen).
Thanks to ALTERNE project, CLARTE has worked on Unreal Tournament technology and more specifically on CaveUT2K3 and became part of the UDN (Unreal Developer Network). CLARTE has implemented stereoscopy on this new release of the software in order to produce an outstanding total immersion experience. This involves implementation of trackers so that the perspective is modified according to the position of the user. The schedule of this work has been the following:
- CaveUT2k3 implemented: Autumn 2003
- Stereoscopy implemented: Spring 2004
- Trackers integration: Summer 2004
