[Paraview] Plotting line data on the surface of a sphere

[Dan Bower]

Hi all,

I am plotting a spherical data volume using structuredgrid.  I also
want to plot line data on the surface of the sphere.  Presently the
line data (list of points) is in an x y multisegment GMT format (i.e.
lat lon)

(1) A crude hack is to mesh the line data and then contour.  This
won't look great and is highly dependent on the resolution of the
mesh.
(2) Use the python filter.  Problem is, consecutive points don't
necessary join to each other (i.e. this is the reason for the
multi-segment -m option in GMT).

Any advice much appreciated.

Thanks,

Dan
