[Paraview] Fwd: (no subject)

Sebastien:

The data file I attached to the previous version of this update note was
too large.

I am resending the note with that file removed.

Update:

I am able to write a ply file using CreateWriter (see attached
first_stab.py and nano....vtp files).
But the ply file is in binary.

I looked around for more than an hour to find out how to write the file in
ascii - to no avail.

Any hints?

Aside: When I put in 0 (for ascii) as a third arg. to CreateWriter,
pvpython complained about
having more than 2 arguments. I note that in the paraview users guide,
CreateWriter has
several arguments in some cases. help(CreateWriter) indicates that more
than 2 arguments
can be used:

>>> help(CreateWriter)

Help on function CreateWriter in module paraview.simple:


CreateWriter(filename, proxy=None, **extraArgs)

Creates a writer that can write the data produced by the source proxy in

the given file format (identified by the extension). If no source is

provided, then the active source is used. This doesn't actually write the

data, it simply creates the writer and returns it.

Regards,
Tim
