[vtkusers] plot3d binary format (old question ?)

What we did was use the plot3d reader as an example implementation for our 
own reader that could swap bytes, handle single/double precission, etc. We 
needed a lot more flexibility when reading the data files in and converting 
the data to other flow properties (i.e. needing thermally perfect gas model, 
curve fit property models).  I don't know of an automatic way of determining 
the endianess of the data file except by having the user set it :(, but once 
you know that (and the endianess of the platform you're running on), then you 
can use VTK's byte swapping code to do the swapping as needed.
