I have a couple of 3D (medical CT, PET, ultrasound...) volume datasets, which I
want to render using povray. I have done this before, and the flexibility (e.g.
being able to include additional 3D objects, using segmented datasets, combine
datasets and being able to deform datasets in time using proper scripts) was
very convenient. However, determining parameters for view, visualization and
others for me was hard to do, we worked right on the script level.

Can anybody recommend a tool like v3d, that allows me to interactively determine
view parameters for volume rendering, and exports them to a povray script for
advanced feature editing? I looked at the software recommended on povray.org,
but all of them seem to concentrate on solid modeling.

Thanks, Frank

Paul Bourke made a nice page about visualisation of 3D scalar field.

Good readings and browsing.

Probably such a beast does not exist, but as far as I can
see v3d is open source (and also has a plugin mechanism) so
you might be able to implement this yourself.

Thanks for the quick replies, I'll look into both. Since v3d already does much
of what I need, it would be great to have an interface, and yes, it might be not
too difficult to build since I need only a portion of the parameters and not a
full export facility that supports every bit of the view.

Thank you, Frank
