Hello,  
first off I do not really know the answer to your problem. It intrigued me because researchers local to me do geotechnical seismic work and your question looked like that sort of data. I think it must be _your_ responsibility to transform the data into a spherical coordinate system because paraview (if it were possible) might only provide points equally spaced and not truly representing the spatial variation of your data. How can it know the metrics for converting from computational rectilinear to spherical coords?

I did google this for you though…

> I am a new ParaView user and would like to understand how to get ParaView to represent the data file I am using in a spherical format. The background is as follows: I initially received a .FITS file containing data on the Sun’s magnetic field. A friend helped me to convert this into a .vtr file so I could view it using ParaView. The .vtr file I have is of type “Rectilinear Grid” and represents its coordinates as X, Y, Z, where each point/cell stores a magnetic field vector which represents the X…

best wishes and happy new year.
