Here's a cool Java3D application about to take the sports world by storm:
http://www.auto-ref.com/pages/711020/index.htm
AutoRef is a system that uses cameras to monitor a tennis game in progress and uses computer vision algorithms to analyze the image and determine where the ball is in 3D space. Then the data is sent over a network to a game play server, and from there to multiple 3D clients (I wrote both the server and clients). Data is buffered, the current score is determined, and 3D displays of instant replays are shown onscreen. The system has been tested at the US Open and even made the newspapers (in response to the bad umpire calls that lost Serina Williams the title):

Auto-ref uses a combo of C++ and Java technologies, with both the client and the scoring server being 100% pure java. Currently the system is set up to render Java3D images to pixel boards in the stadium, television broadcast, a handheld device used by the line judge, and the referee's laptop. The system is currently accurate enough to have less than 3 millimeters of error.

That is the question Matthew Schmidt ( [EMAIL PROTECTED] ) from JavaLobby is asking in http://www.javalobby.org/nl/archive/jlnews_20040914o.html If you have something to tell drop him a email.
There is also aforum topic about Java3D at JavaLobby: http://www.javalobby.org/thread.jspa?forumID=61&threadID=14447
