Re: [JAVA3D] Why does translation affect rotation values

Nikolai,

See if the following modifications are what you're looking for:

 .....
 t.getRotationScale(rotationScale);

 // begin mods:
 double tscale = t.getScale();
 rotationScale.mul( 1.0 / tscale );
 // end mods:
 .....

Your test results should now be identical.

It gives another result yes, but not the same as input.

But I had some compile problem last time I tried this it seems, because it now looks 
like setScale(1d), before I get the rotation helps to get the correct result. At least 
in this specific numerical case.

But still this should be regarded as a bug, since I beleive
AxisAngle4d.set( Matrix3d ) should do this automatically.

Quat4d has same problem.
