I've tryied it many times: regardless if I comment out setTranslation or not, the outputs are different.
Outputs are the same *only* if I comment out setScale from your code or set the scale value to 1.0d. Are you sure you're recompiling the program after commenting the setTranslation ? I'm using jdk 1.4.2 & java3d 1.3.1 Cheers, Florin -----Original Message----- From: Discussion list for Java 3D API [mailto:[EMAIL PROTECTED] Behalf Of Nikolai V. Chr. Sent: Mittwoch, 28.

Well if I comment out setScale it works fine, but if I comment out setTranslation it also works fine, so translation must be involved in the process somehow. I cannot just revert the setScale. If I try to do a t.setScale(1d); the rotation still comes out the same. If I try to do a t.setScale(2d); same bad result. But do you suggest any workarounds? The rotation is not corrupted inside the matrix4d, since my model displays correctly translation, scale and rotation in my 3D world. So somehow I should be able to retreive the rotation, it must be there, otherwise it would not be drawn correctly. Is the corrrect Matrix4d inside the retained node only, and the normal matrix4d is corrupted but displays correct since it is not even used for displaying, the retained one is?
