My project uses VTK, CORBA and MPI. But CORBA and MPI are only used to
send parameters from client to server, once the VTK computaion is done,
I used VTK's socketcontroller to send data back to client. For my understanding,
the difficulty to use CORBA with VTK is I don't know how to serialize VTK's
objects, while VTK's own functions make this transparent to users...good
luck!

<p>I'm currently investigating the topic mentioned in the subject and I'd
<br>like to collect some tips from this mailing list to avoid possibly
<br>going in the wrong direction or re-inventing the wheel ?
<p>A search in the mailing list archive showed that few people asked for
<br>CORBA which makes me wonder. Also there's a paper on parallelizing
vtk
<br>with the aid of MPI (the classes in vtk's ?Parallel? folder seem to
be
<br>modeled after this paper) which analyzes the situation correctly but
<br>(that's my impression) goes into the wrong direction in implementing
<br>everything that RPC tools like CORBA provide for free under the hood
of
<br>MPI.
<p>Did anyone here implement a distributed vtk application with either
<br>plain SunRPC, COM, Java RMI or CORBA? I'm especially interested in
<br>distributed visualization pipelines (pipeline parallelism over network
<br>boundaries, asynchronous calls, Mtime handling). I guess, I'll start
<br>with reworking the vtkOuputPort / vtkInputPort into CORBA, but the
<br>inner workings of the pipeline update mechanism are still a mystery
to
<br>me.
<p>Some links to material on the web would also be very helpful to me.
<p>BTW: This is what I found so far (and it's not much):

<p>vtk and CORBA:
<p>(from my understanding, they don't use distributed visualization
<br>pipeline but use CORBA to invoke python on remote hosts - is that
<br>correct?)
