sun visualization system was a sharable visualization product introduced by sun microsystems in january 2007. it used other sun technologies, including sun servers, solaris, sun ray ultra-thin clients, and sun grid engine. the sun visualization system software was based on several open source technologies: chromium to perform distributed 3d rendering, virtualgl to re-route 3d rendering jobs to arbitrary graphics devices, and turbovnc to deliver the rendered 3d images to a client or clients. sun sponsored and/or contributed changes back to these projects throughout the life of the sun visualization system.
