[vtkusers] multithreading java applications

[Sebastien Jourdain]

Hi Jonathan,

VTK is not thread safe at all. So you first should be aware of that.
Then any Swing call should be made in the EDT (event dispatch thread.
SwingUtilities.invokeLater..)
To get a more precise answer, you will need to be more precise in your
multi-threaded case...
Once the VTK objects are connected to the renderer, they should only
be updated through the EDT.
