[vtkusers] [Paraview] paraview won't read plot3D files

[da]

Hi Rick,

Got the email. I can't open your binary files either. I'm going to guess
that this is a precision issue - have you tried writing the files into
single precision binary and trying again with Paraview? This won't matter
for ASCII cases but makes the difference for Binary. The plot3d reader
currently works only with single-precision.

Paraview does not support function files. You will need to modify the
vtkMultiBlockPLOT3DReader (or write your own) + paraview plugin for that.
