It seems that it might be covered in the 
http://www.vtk.org/Wiki/VTK/FAQ#How_can_I_stop_Java_Swing_or_AWT_components_from_flashing_or_bouncing_between_values.3F
FAQ . I will try that tonight. Hopefully, this will help...

Well, my intention was to use the available class (for example
vtkRenderWindowPanel) and send to my C++ layer a reference to the renderer
and cast to to a native vtkRenderer and then work on it in C++ (I am quite
new to vtk so this might be completely wrong). When done with it I would
request a repaint from java, so that the screen get's updated...  Does that
make sense or am I going in the wrong direction? Would that prevent the
threading issue your are mentionning?  I am quite close to get an
environment where I can start testing this, so hopefully I can answer some
question my-self, but please let me know if you believe this is really a
wrong approach.

Thank you again

Nicolas
