[Paraview] Re: Possible Endian Issues on Paraview OS X Intel

[Mike Jackson]

I took the same data file that would NOT load in Paraview and wrote  
this small program to load and display it. The program works fine  
compiled against vtk 5.0.0

I then compiled/Linked against the build of VTK that Paraview uses  
and low a behold the same error occurs. So if I am using Paraview  
2.4.4, what version of VTK am I using? Can I substitute in VTK 5.0.0  
for the VTK that is in Paraview 2.4.4?

Thanks for any help.
