plot3d file reader is broken.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
From an e-mail from Robert:
I went digging for an hour and adding 64bit support was really easy ( ie I did it). The problem is that I was wrong on what was causing the error.
I researched more about plot3d and figured out the file is actually 32bit Fortran. The reader issue is that currently it is broken when reading in multiple grid files. I was able to locate other multiple grid plot3d files and they don't load in properly.
It looks like bugs http://vtk.org/Bug/view.php?id=2948 and http://www.vtk.org/pipermail/vtkusers/2003-March/065955.html will both need to be fixed and I will need to sit down with the spec a bit longer to determine any other issues with multiple grid support when reading from fortran files.
