[vtkusers] parallel vtk - looking for dummy user docu

[Wagner Sales]

Peter,

Sometime ago I asked by this too. The answer was at the end of this
mail. But, will be very good if someone haves working examples or
simple codes and can share in this list.
The test and examples in VTK are a start point, but I think not an
ideal start point.

Best regards,

Wagner Sales


You might want to look at IceT, which is included in the ParaView source code.

My apologies if the rest of the email is pedantic for you.
The basic task is to:
1) split the volume up amongst the processors - this can be done by
assigning each filter a separate update extent or using extract voi or
different files for example
2) volume render each processor's sub volume locally, all using the
same transfer function, viewpoint etc
3) decide upon a back to front (or possible front to back) ordering
for the subvolumes
4) communicate the locally generated images, including alpha, across
the network and
5) alpha blend each image in turn to produce the final result
