The RotationInterpolator completely replaces the existing transform
matrix in the target TransformGroup, including the translation
components being set to 0,0,0.
=A0
Add another transform group above the TG that holds the translation to
(3,0,0).=A0 Use this new transform group as the target for the
interpolator.

Subject: [JAVA3D] Help! : rotation of object
There is a TransfomGroup node that have (3, 0, 0)) by its translation
component.=20
and then I made rotationinterpolator. Its target TG is above
TransformGroup node.=20
however the rotationinterpolator rotates at origin.=20
Why?=20
Actually, TG has translation component (3, 0, 0).=20
Transform3D t3d =3D new Transform3D();=20
t3d.setTranslation(new Vector3f(3.0f, 0.0f, 0.0f));=20
TransformGroup objRotPos =3D new TransformGroup(t3d);=20
rotInterpolator =3D new RotationInterpolator(alpha, objRotPos);=20
Anyone Help me~~~~=20
