Dear Paraview community, I am trying to use Paraview to render a volume composed of several slices acquired with a microscope. Due to our method of data acquisition, the slices do not line up exactly. They are skewed at a certain angle. So the image stack is shaped like a parallelepiped rather than the conventional cuboid shape. The nrrd file format seems like a good candidate to allow us to render these skewed volumes since nrrd allows one to relate data space with physical/global space by setting the "space directions" property in the nrrd header file (see below).
I have written the nrrd header file as below, but I cannot get Paraview to render the stack correctly. It just renders the stacks in a cuboid shape as if I never even set the "space directions" property. Have I written the header file incorrectly, or am I forgetting something? Or maybe paraview cannot make use of this metadata? I have double checked my geometry, and I believe that the space directions vectors are correct. NRRD0005 type: uint16 data file: stack_2560_2160_200_uint16.raw dimension: 3 sizes: 2560 2160 200 spacings: .325 .325 5 space directions: (.325,0,0) (0,.2815,.1625) (0,-4.3301,2.5) thicknesses: nan nan 5 encoding: raw endian: little Thanks for your help, Cody Greer Washington University in St. Louis
