Thanks for your kindness.

In fact, I have more than 1000 objects. I can get their positions from
an ASCII file. Therefore, I used a 'for' loop to put them into a show
window.
My objects were spheres. That's why there was an 'orb' in my code. In
this step, I don't have any more questions.

But now my objects should be changed to some kind of air ballons,
which has hard shell with a radius of R1 and air-kern with the radius
of R2(R1>R2). Some of them should be cut(e.g. instead of the whole 3D
region just to show part of it) , in order to show their hollow
kern.

Is it possible to make my aim come true with 'XOBJVIEW'?

Thanks,
Danyang
