[vtkusers] VTK6 and Java Examples

[Sebastien Jourdain]

Hi Ric,

you are correct those wiki example seems to be out of date specially since
the modularization of VTK where all the libraries have been renamed and
shift around.

The best place to look for up-to-date examples is in the vtk.jar itself
which should contains a set of sample code with the proper usage of
rendering and GC classes as well as the loading of the libraries.

And Gerrick just beat me... ;-)

Good luck,

Seb
