[vtkusers] Refresh Render

[pablo p del castillo]

Hello,

I have a simulation program, it is finite element calculating deformation nonlinear using a iterations . When the solver is finished, i can postprocess the solution with vtk pretty good.
Now i would like open the postprocessor when the program start and every n iterations refresh the render actors.

Is it possible?, is there any example?

Advanced thanks,

Pablo
