<DIV><FONT face=Arial size=2>Dear all:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> Is there an efficient way to convert?
Now, I am doing the 3D correlation computation between two poly datasets (one
from a CT volume), and the other one is a 3D sphere (as kernel) using <FONT
size=2>
<P>vtkImageCorrelation by setting the dimensionality to 3. </P>
<P>The vtkImageCorrelation takes imagedata as input. I tried the <FONT
size=2>vtkPolyDataToImageStencil to do the conversion, however it did not work.
Or, any one could give me some suggestions how to do the 3D correlation by using
other vtk class for two vtkpoly datasets.</FONT></P>
