[vtkusers] vtkImageReslice speed

[Lyubomir Zagorchev]

I am using vtkImageReslice to cut three orthogonal cross sections from a volume.
I noticed that if the volume has axial dimensions greater than 256 the performance 
of the filter becomes very slow ( even if the axial dimensions are 257, the speed
decreases significantly). Could someone briefly explain what is the reason for 
that? Can I do something in my code that will increase the speed of the filter?

Thank you,

Lyubomir
