I have created a 2D deformation field from a 512*512 .png image using ITK and the example file: BSplineWarping1.cxx. The deformation field is stored in a .mhd file and a .raw file.
In paraview (3.6.1 for windows) I open the .mhd file. Next I choose the calculator filter and type the following expression in the expression field: MetaImage_X*iHat+MetaImage_Y*jHat+0*kHat where MetaImage_X and MetaImage_Y are selected from the Scalars menu. Next I press apply. Next I select a glyph filter when standing on the calculator. When I press apply an empty 3D coordinate system appears without any deformation vectors. When I press the Information tab in the Glyph filter I can see that: Data Arrays: Name Data Type Data Ranges MetaImage float [-inf, -1e+38], [-inf, -1e+38] GlyphVector float [ 1e+38, -1e+38], [ 1e+38, -1e+38], [ 1e+38, -1e+38] Could this maybe have something to do with the lack of deformation vectors? Or are paraview not compatible with deformation fields created with ITK? _______________________________________________ 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
