[Paraview] Plotting 3d point data in paraview

[David E DeMarle]

Try using a 2d point instead of a 3D sphere to cut down on the
rendering load. Also try using the point sprite plugin. The display
will let you scale and otherwise adjust the appearance of the points
according to the data values.

I output data from Fortran to a .vtk file using the polydata dataset followed by the point_data for each particle. (I output the data in ASCII format at the moment, still not sure how to do the binary output with Fortran..) Loading the resultant vtk file into Paraview and using the Glyph filter I can assign a sphere to each point and get a good plot of the 3D position using the default Glyph filter options (max number of 5000 points).

I am trying to plot around 190000 particles and if I set the filter to plot this Paraview just chokes! I have done such plots in the past using Tecplot so I know this isn't impossible.
