Dear Colleague, we have been asked to extend the submission deadline for RT07. The new deadline is this Sunday (17th of June, midnight CEST). Also, please note that submissions for RT07 do not have to be interactive or real- time; any research related to ray tracing is within the scope of the symposium ... Check out the web pages http://rt07.uni-ulm.de and the call for papers http://www.uni-ulm.de/rt07/News%20%26%20Downloads/News%20&%20Downloads_… Best regards, -A. Keller and P.
