here. I was able to read my image in and I thought that I was creating a
slice that was at 45 degrees to the entire volume (cut the entire volume
diagonally). However, the only thing that seems to be happening is that I’m
taking the topmost layer of the volume and rotating it by 45 degrees. <o:p></o:p></span></p>
