Hey Matt,

I've been a little busy, hence the slow response.

IIRC there is also a little extra work needed to get the data ranges
and stuff so it works nicely with mayavi and its module manager etc.

Thanks for the compliments, the screenshot is really cool.

The student did get a fully working patch against the then mayavi svn
trunk but there were a few issues I wanted addressed and I gave the
problem over to another student who has been busy with other work and
has also not picked up enough to take it ahead.  I am hoping this will
be resolved by this month end though.  I've been pestering the student
to get this done ASAP.  Right now he is working on a couple of
features and will start this work next week I hope.

cheers,
