Greetings, Naveen,
Just to save the big guns from sending this out, I'll offer that one
problem right off the bat is that your series of rotations
Rot.rotX(angleX);
Rot.rotY(angleY);
Rot.rotZ(angleZ);
results in only Rot.rotZ(angleZ) being the net effect.
hello
i am facing some problem like angle seting with x y z planes . my basic problem is "I
NEED TO PLOTE A CYLINDER IN X Y Z PLANE with some dynamic anggles "
i am using below code

I've never used it, but there's a Cone primitive (with two radii) in the

Rob,
If they'll make java3d open source and move it to games.dev.java.net, let's
say in the games-middleware category, there'll be lots of enthusiast peoples
(like me) which will gladly contribute on making java3d to stay on top of
the games-core api's.

Florin,
I think I understand your proposal now. This seems a lot more reasonable. This
approach, as I'm sure you are aware, has lots of synergy with approaches
elsewhere in Java, such as the various SPIs (Service Provider Interfaces) in
things like JNDI and ImageIO.
Anyhow, this might all be acade

I fear you are right about the RFE nature of this. I'm hoping that maybe there's
some undocumented run-time flag that the j3d folks might be able to share with
us to force the building of the geometry arrays.
