You might be surprised that the website of the VRIPHYS workshop has disappeared. At the moment, this link: http://www.vriphys.org does not work any more.
The main reason of this is because it has been decided to change to a different host provider for the website. Hence, the previous Italian provider (aruba) does not host the vriphys website and has therefore removed the information.
Vriphys will be now hosted and managed by INRIA, France. Find the latest 2010 vriphys (the 7th) workshop in this link.
As a partner event of Eurographics, you can find the papers and scientific committees of the previous workshops in the Eurographics Digital Library. HERE
Note that papers of the years 2004 and 2005 are not available in the Eurographics website since, although partnership with EG was obtained in 2005, it was until 2006 that they started to store the papers and related information.
In any case, if you need the vriphys papers or other information related to 2004 and 2005, feel free to contact me.
