non-planar slicing. Imagine a sheet of paper curled into a parabola or<br>half-ellipse, in the middle of a 3D volume. I want to extract the points on<br>the sheet of paper into a flat 2D image. (If there is a better/standard term<br>
for this, please correct me). The curve would be defined by a poly-line or<br>Bezier.<br><br>AFAICT, the closest thing in ITK is ResampleImageFilter(), however I'm<br>having trouble figuring out what the transform would be. All the examples<br>
seem to map 3D to 3D. Or is this the wrong approach to begin with?<br><br>Can anyone point me at something similar?<br><br>--<br>View this message in context: <a href="http://itk-insight-users.2283740.n2.nabble.com/Non-planar-slicing-tp7580206.html" target="_blank" style="color:rgb(17,85,204)">http://itk-insight-users.2283740.n2.nabble.com/Non-planar-slicing-tp7580206.html</a><br>
