It sounds to me like the OP wants to take a profile, and rotate that
to produce an object, much
like we did back in the '80's on our 8bit home computers to draw 3D
wireframes.

He/She might like to look at REVOLUTION_IDL at
http://www.ittvis.com/codebank/search.asp?FID=473,
written by ITTVIS's own Basquette-case, Eduardo - the Sales Manager
for Oz, of whom I cannot
speak too highly, especially when he's slumped under the table after a
few local beers...

But, Eduardo's drinking habits aside, I can recommend Revolution_IDL
to the Object illiterate, and to those who just
wanna have fun!

Cheers,

Andrew C.

Unless I completely misread what the original poster was
asking about, I don't think is going to help. All input
to iVolume and IDLgrVolume are volumes, not vectors. I don't
know of a way to create a volume out of three vectors.

Cheers,

David

Of course.
Take a look at iTools for a quickly solution http://www.ittvis.com/idl/idl_itools.asp
Also take a look to object graphics (http://idlastro.gsfc.nasa.gov/
idl_html_help/IDLgrVolume.html)

Bye.
