If you look at forums of java.sun.com and Java3d
particularly you will notice that someone is talking about j3d.org which
pontentially may contain relevant class.
I cannot find anything in j3d.org

Jack,
Whew! It took a while to locate that stuff (I'm
still a J3D novice)! Is there any documentation about what's in there, or do
you just have to crawl around in the source for a while? How would you ever
find a thing called "Quadrics"? (not that you could use it, because it's not
public).
Well, now that I found it, I tried to use it via
the various Cone delarators, but there doesn't seem to be a Cone with 2
radii.

That's where it is. You should be able to decipher the calling
sequences from the Cone and Quadrics sources.

Do you mean com.sun.j3d.utils.geometry?
Otherwise, what is the correct class? ANd what about the constructor in
order to generate the shape.

BTW, I've never used it, but there's a Cone primitive (with
two radii) in the Quadrics class of the Sun geometry utilities. This is
the class called by Cone.
I'll probably just add a TriangleFanArray
to the top and bottom. You can probably do that temporarily until I
get around to it.

I would appreciate if you deal with
making the frustrum solid.

Well, actually I just didn't need it
for what I was doing. I used two of them to build something that
looked like the nozzle of a fire hose for an Information
Visualization demo I was doing (see the Emergencies Demo on my web
site). If I get a chance, maybe I'll add top and bottom caps as an
option.

That's better, but the shape is not
solid, why that?

Oh, sorry. I didn't notice that
your 4th parameter (the number of quadrilaterals needed to
define the cone) was set to 2, making it flat. Try something
like 16 or 32.
Also, the comments lie about that
parameter defaulting to 16. I forgot to test for a null
parameter there.

The parameter is a java.awt.Color Color, not a
Color3f.
Try: AttenuatedCone
frustrum=new AttenuatedCone(1.0f,0.5f,1.5f,2,new
Color(0.0f, 1.0f, 0.0f),0.5f);

When I needed one, I did
this, and called it AttenuatedCone. It's a set of
quadrilaterals arranged around the top and bottom
"hoops" like a barrel. I hope the comments explain
what I was after.

Is there such a class.
