Hi Mathias, > In Ugo?s Tutorial one can see how to make slices of data. That?s working > fine if I would only like to make slices that are parallel to an > arbitrary axis. But what about warped slices? I implemented that by > reading out the samples of my data-object and find the nearest > neighbors. Then I set all other samples to null just to make them > invisible. That works fine but is slow and complicated. I wonder if > there is a way to use the resample() method of FlatField to implement > warped slices? Are there any approaches? Yes. You can define a Gridded3DSet with manifold dimension = 2 that defines a warped slice or even a curved surface, and pass it to the resample() method of your FlatField. The main problem is to calculate the 3-D vertices of a 2-D grid that lies on your warped slice. A geometry problem.
