This package contains simple visualization scripts which work similar to Matlab's quiver, quiver3, trisurf or related functions, but in contrast, they pipe the data to vtk-files which may be called and visualized via Paraview, Mayavi2 or others. Once you have selected the datasets you need, you can download files in local reference frame if you want to test registration algorithms and compare your result with pose_scanner_leica. This is useful for the visualization of functions with 2/3-dimensional graphs since it allows postprocessing by paraview. mrml file can be opened. format — The means by which the data values themselves are stored in. Perhaps fclose() is not working properly or the saveas() is not closing the file. pvsm - the ParaView state file. ITK is a powerful open-source image analysis toolkit, but it requires the knowledge of C++ to use it. As you said, the new format is an xml format. This example uses the finite elements method.
