[Paraview] Plotting data on/in a sphere - update to earlier post

[Lester Anderson]

Hello all

Further to my earlier post, I have managed to work out 
how to get point data into Paraview in spherical coordinates using the 
following:

X=Radius * cos (longitude) * cos (latitude)
Y=Radius * sin (longitude) * cos (latitude)
Z=Radius * sin (latitude)

All angles in Radians. The radius is the earth distance, for which I computed 3 depths (50, 100, 150 km) - in radius this
works out as 6328 km, 6278 km and 6228 km (with fixed radius at d=0 as 6378 km).

Calculated
 a CSV file for input to Paraview and then did table to points which 
works fine, table to structured grid is more awkward.

Is there a way to take a point dataset (vtk) and convert it to a structured grid so that one can actually slice the data?

I have done a test VTK file and the input CSV, but are too large to post to the list,.

The modelling idea is to generate a mantle "shell" that can be sliced properly to visualise mantle velocity anomalies. The full data file
consists of 56 layers in 50km intervals and is quite large as a CSV file 350Mb+  The table data is all correct but it vauses Paraview to crash out of the import.

One option to get around the import issue is to load up the layers separately and I guess just use the append dataset option.

Thanks
