Hi,
About one year ago, I got some C code from the VisIt site from LLNL,
which allows you to write legacy (.vtk) files using quite easy-to-use
wrapper functions. It writes both in ascii and binary and checks for
correct endian. I googled for the filenames just now and found them
here: http://www-vis.lbl.gov/Vignettes/SNAZ/visit_writer_float/
I cannot write binary data to newer XML files since I understood that it
has to be in base64 encoding and I wanted to export my data without
using external libraries such as vtk. If there is an option to write
binary xml files, I'd like to hear about it.
Regards,
Ivo

Hi Ken
Thanks for the info. So is there an easy way to take the ascii data
and make it into a binary file (big-endian or ortherwise), or is it
more involved? Basically I have my data already it just needs converting.
Cheers
Lester
