LATEST NEWS: Franck Vernel has provided a French translation of the documentation of LiveGraphics3D. Thanks a lot, Franck!
VERY IMPORTANT NOTE: The current version of LiveGraphics3D 1.90 does not work with Mathematica 6.x, only versions of Mathematica prior to version 6 are supported. I might be able to fix some of the problems later this year.
ANOTHER IMPORTANT NOTE: As reported by Hans van Assen, the implementation of the Max function has a bug (it always returns a positive value) in the current version 1.90. I'll fix it with the next update; please use If or Min instead. Sorry about this.
Yet another important note: The current version of LiveGraphics3D is 1.90. Nonetheless your browser might read an older version of the LiveGraphics3D applet (1.83 or less). If reloading the page does not help, deactivate any proxy, clear all caches and restart the browser. Then view the page again and things should work fine. (After this you should activate your proxy again.)
