I presume those two "data sets" are either IDLgrModels or
object graphics primitives, right? Otherwise, you are blowing
smoke thinking they can be used in XObjView. If they *are*
what they are suppose to be, you can send them in an array
to XObjView:

You can do whatever you like in object graphics if you
have infinite patience and a capacity to endure days
of frustration. :-)
I mean, yes, you can do this. You will have to add texture
maps to your polygon objects and then use the alpha blending
capabilities of IDLgrImages (your texture maps) to create
the illusion of transparency.
It's all just a little beyond the normal hand-holding
of this group, however. You might want to get ahold of
Ronn Kling's book Power Graphics with IDL. That will
get you up to speed fairly quickly, I think.
Cheers,
David
