Does anyone know of a Quarternion class for Java3D?

Has anyone here been sucessful creating quarternion fractals in J3D?

I'm a  bit rusty, havent done any J3D coding for over a year now, but
now I need to experiment with 3D fractals, and I know J3D will work,
so stay tuned.

No new posts in two days? I figured this newsgroup would be buzzing

I translated a Paul Bourke's QUATERNION.c Class to J3D.yesterday.
Still trying to validate it. Once I'm sure everything is right, I'll
post it here.

By the way, the J3d Quat4d class doesn't work well for Fractals, the
main problem is it normalizes all quaternions. Which in itself can
create some interesting images, but it's a pain in the a.s to work
around. I don't understand why it was done this way, there's a
normalize method in the class! I haven't checked, but I think the
maths are different as well.

Anyway... still haven't made figured out how to do a julia rotation
fractal in 3D yet, but I will.

Take care all  :-)
