We've done this in our visualizations by allowing the user to use two
picks or a probe list in the scene. The user can manipulate one probe
for the center the other for the outside axis and then render some
plane through it. You can also use three probes if you need truly
arbitrary planes. Then from the probes, construct the plane center
vector and normal vector.

Hello again :)
I have a 3-d scalar data set, and I map it to a 2-d scalar data set
with MapToPlane. Is there a way to get a better control than the way
supplied by 2 vectors (position and normal). I know I can use the
slab and make it move back and forth, but I want an arbritary plane
and as far as I know, the slab does not do that.
Basically I want to be able to rotate the plane almost as easily as
the viewdirection.
And I still have not solved my other issue (above) :)
Any hints?
Arne
