Hi, first of all I would like to thank You all for your work on this project, because we are using your software regularly for short three dimensional presentations to our students at Lorand Eotvos University, Hungary. I am working at the Faculty of Natural Sciences as a software engineer and we have a large stereoscopic projection system and we are just about to finish the development of our head tracking system, which is already able to measure the position and orientation of the viewers head. This way we will be able adapt the viewpoint of the three dimensional software to the viewpoint of the user. In order to completely interface our system with your software we need to modify it or write an additional module. Would you be so kind to help me find a sophisticated (or maybe easy) way to upload/adjust the cameraposition (world transformation) through an interface to your software? Thank you very much in advance. Regards, Thomas Borsos
