I think what your asking is "why does my object move when I rotate it?"
=A0
Well, again I assume that you have a Shape3D under a TransformGroup, =
and
you are rotating this transform.=A0 Rotations occur about the origin of
the transform, so if the transform has any non-zero translation
components, the object will move about the origin.
=A0
You may want two transform groups:
=A0
=A0=A0=A0 TG1
=A0=A0=A0=A0=A0 |
=A0=A0=A0 TG2
=A0=A0=A0=A0=A0 |
=A0=A0=A0 Shape3D
=A0
Perform the rotations on TG2, but the translations on TG1
=A0
Hope this helps.=A0 If not, show some code snippets or a depiction of =
your
scene graph.

Subject: [JAVA3D] Could you help me in any question?
=A0
Could you tell me i can do when:
=A0
if the object is rotated in x, y, z. it moves with the object instead =
of
stay fixed.
=A0
I'd like to know how rotate my obect when this happened axles ( x , y =
,z
) rotate together with my object.
