Hi Ting,

I'm not sure what you meant. Right now I initialize the filter and call 
the Update() method. But this can be done only once. All iterations are 
computed. How do I execute just one iteration and return from the 
filters execution?

I saw the generatedata method. This is where you iterate until m_Step 
equals m_StepThreshold. When this is true you exit the deformation loop 
and call computeOutput. Then the method returns. By now all the 
iterations are already computed.

When I try to call Update() the second time to repeat the same number of 
steps the filter crashes with the following stack trace I attached at 
the end of the file. Is it allowed to call update a second time and when 
yes, why is the program crashing?

Bye
Thomas
