We have one main routine to generate Paraview output for data that is either stored in a GeoData structure (that has lat/lon info), or ParaviewData, CartData (Cartesian).
If GeoData is supplied it is internally automatically converted to the right format. Vectors, such as velocity, are also converted accordingly.
You can also visualize time-dependent data, or combine existing paraview files into a *.pvd paraview collection (that can be used to show a movie)
