Thanks for your response. A few more questions.

Depends what format you are talking about. Converting to legacy VTK,

Apologies for not knowing about legacy VTK. Does this imply that the
newer VTK uses C ordering by default? If so, in what version did it
change?
Thanks again.....John Cary
If you are knowledgable to program in hdf5 you may consider writing a
plugin that will import your data without file conversions. However,
you will probably have to convert rank-2 arrays anyway:
// FIXME can it be done smarter
for(int j=0; j<array->GetNumberOfTuples(); j++)
{
for(int i=0; i<array->GetNumberOfComponents(); i++)
{
array->SetComponent(j,i,data(j+1,i+1));
}
}
where data is a fortran style array. I wonder too if SetData would
work here.

I have arrays written out from C into HDF5 using the HDF5 C
API, and so in the file the arrays are in C ordering. I now
need to read them into VTK. AFAICT, VTK is Fortran ordering,
even though it is written in C++. So that means I need to
reverse the ordering. Of course, I can write a loop to do
this, but is there some standard way that VTK folks do this?
I don't want to reinvent the wheel.
Sorry for what is likely an elementary question, but I could
not find it on the FAQ or after googling quite a bit.
Thanks so much......John Cary
