Depends what format you are talking about. Converting to legacy VTK,
yes, this is inefficient in every regard. 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
