Hi all,<br><br> I have a set of 2D .png slices that I read into VTK using vtkPNGReader.<br>I have no clue where the data goes after that.<br><br> While I would like the 3D volume display, I would also like to have a display of the individual 2D slices, without having to use more memory. <br><br>The following is the code I use to read the .png slices.<br> vol2 = vtkPNGReader::New();<br> vol2->SetFileDimensionality(2);<br> vol2->SetDataByteOrderToLittleEndian();<br> vol2->SetFilePrefix ("2938/2938.png");<br> vol2->SetDataExtent(0, 255, 0, 255, 0 , 31);<br> vol2->SetDataSpacing (1.0, 1.0, 4.0);<br> vol2->UpdateWholeExtent();<br><br> I've always stored data in a n*m*k matrix and so its easy to traverse along any given axis.<br><br>In VTK, I'm not sure how to do this.<br><br>Does anyone have any suggestions ? Where and how is the data stored in vtk
