<DIV><FONT face=Arial size=2>Hi Shyam,</FONT></DIV>
<DIV><FONT face=Arial size=2> Thanks for ur suggestion.
</FONT></DIV>
<DIV><FONT face=Arial size=2> Let me explain my
problem in detail. I am applying MIP function on the input volume and rendering
it to view it. Now i want to select the ROI in the rendered volume, clip the ROI
and store the ROI in a file. I have my own algorithm of ROI. Now the
problem is with saving the ROI. For saving ROI or atleast the entire rendered
volume, i should get the rendered volume into a buffer for further processing. I
think we can get the redered volume only from vtkrenderer or vtkrenderwindow or
vtkrenderwindowinteractor. I could not find any function which serve my
purpose. </FONT></DIV>
<DIV><FONT face=Arial size=2> I found a
function "GetPixelData" in vtkRenderWindow class which returns the pixel data
visible on the vtk window. But it is just a slice. What i want is the entire
volume which i gave as input. I mean if i give, lets say, 10 images as
input<FONT face="Times New Roman" size=3><FONT face=Arial size=2>, after
redering i</FONT> <FONT face=Arial size=2>should able to get 10 slices as output
in a buffer for further processing. Is there any class which exposes a function
which help me in this regard.</FONT></FONT></FONT></DIV>

the classes i am using.</FONT></DIV>
