Hi Helder,

what vtk classes do you use ?

I work with a vtkRenderWindow (vtk4.2.2, g++ 3.2, SuSE8.1) and call the
Render() function in a loop, in which 3D data are changed - works fine.

If you're interested, go to the cvs repository of

http://sourceforge.net/projects/echempp

and look into the directories

GUI/Visualization
GUI/Visualization/test

there are files beginning with Vtk, e.g. VtkPage corresponds to a 
vtkRenderWindow.
The animation is then tested in the test program VtkVisualizationTest.cc


However, I don't know how to realize an interaction while this animation 
runs (rotations, zooming,...). Any idea ?
