RotationZ3D in Java/Javascript

Hi,
Which is the difference between the Java and Javascript versions of Rotation3D elements?
As you can see in the attached files, in the Javascript version the Ellipsoid3D on the left is misaligned.
Regards.

Hi,

Finally I it figured out: the Rotation?3D elements are applied in the opposite order in JavaScript.

My excuses for not participating earlier. I lost the previous email.

The only difference I can think of is that the rotation in JS is always applied with respect to the origin, not the center of the element.

But now that you mention this other difference, we'll have a closer look at it.
