GrImage (Grid and Image) is a test-bed dedicated to interactive applications. GrImage aggregates commodity components for high performance video acquisition, computation and graphics rendering. Computing power is provided by a PC cluster, with some PCs dedicated to video acquisition and others to graphics rendering.
GrImage is a join initiative of computer science researchers from computer graphics, artificial vision and parallel computing. On going research projects are related to:
Part of the technology developed for Grimage is commercialized by the 4D View Solution company.
You can find examples of 4d datasets in the 4D Repository website.
A set of digital cameras enables real time video acquisition. The main goal is to rebuild in real time a 3D model of a scene shot from different points off view. A display wall built around commodity video projectors provides a large, very bright and very high resolution display. The main goal is to provide a visualization space for large models and real time interactions. If extra computing power is required or for collaborative and multi-site experiences GrImage is connected to the i-cluster 2 cluster and to the french experimental grid platform Grid5000 through a high performance network.
Grimage in the media:
The full-body Grimage platform will be presented at Siggraph Emerging Technologies in New Orleans from the 3rd to the 7th of August. More information can be found here.
The GrImage platform in it's portable version was presented in Paris at the "Ville européenne de la science" (European science city) exposition that took place in Paris from Friday 14th to Sunday 16th of November.
The platform was presented in the Inria's "Digital village". At this occasion, we were filmed by the french TV channel TF1. Here is a link to the TV report.
The GrImage website has been updated. This update includes a lifting of the website's look and feel as well as the integration of a popup system for images. There were also some fixes concerning the images. The videos are now embedded within the pages for easier viewing.
Future updates will include :
Grimage and its sister platform built by the i-parla team were showcased at VRST 2008. Both platforms enabled two different users to meet in a common virtual space and share virtual objects. Click here to view the video.
The GrImage platform demonstration at the ECCV 2008 conference. Application to telepresence. See the video
A small-scale GrImage patform has been built for external demos. It has been showcased at SIGGRAPH 2007 EMERGING TECHNOLOGIES, San Diego, from the 2 to 9 of August 2007. See the submission video.
The GrImage platform is hosted by the INRIA Rhône-Alpes. The INRIA project-teams involved in the GrImage initiative are:
