Hi, I asked a related question a couple of years ago but never found a good answer. I need to revisit it now.
I'd like to view image data plus track data in paraview. The track data is produced as list of points in world coordinates. I can convert these to vtk objects and load them. My problem is viewing the image data so that it is placed correctly relative to the tracks. The transformations in the image header can be used in ITK to locate voxel values at then ends of tracks, so I think they are set correctly, however they appear to be ignored by paraview. My very rough check was to use the ruler to determine the coordinates of image corners. One of these was zero, so the header information was being ignored, as the origin was somewhere near the brain image centre. One option appears to be to convert the transformation information from the image header to the transform array in the image Display panel, which is a bit tedious. I'm wondering whether there are 3D image formats that can be viewed using volume rendering in paraview that might do this automatically. So far I've been using mha files created using the ITK too ConvertBetweenImageFormats from nifti. Alternatively, does anyone have some other procedure for viewing combinations of image and mesh/line objects in paraview? _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
