[Insight-users] why vtkImagePlaneWidget run extremely slow after itk::BinaryThresholdImageFilter excuted several times

[Luis Ibanez]

Hi kdsfinger,

Thanks for posting the code and the link to the original web site.

What exactly is running slower ?

Does the user interaction with the planes gets slower ?

or is it every subsequent execution of the BinaryThreshold filter what
gets slower ?

Also: have you reload different images ?
Looking at the code it seems that this applications should only be
used for loading an image once.

After every reload of the image, it reconstruct a large number of
classes without necessarily clearing their previous instances.

Have you checked the memory usage ?
There may also be a memory leak that results in your program to
start swapping to disk....


   Please let us know,


        Thanks
