Thank you! Quat4f#normalize() seems to do the job!
I have a class 'LocationData' that holds a Matrix4f for position and
orientation and some Vector3f for velocity, angular velocity, acceleration
and angular acceleration.
This is somehow unsatisfying bc. I think position/velocity/acceleration

The problem could be due to rotational shearing affects, although it looks like Java3D
normalizes the matrix when getting and setting the rotation values. I would try
normalizing the interpolated quaternion before setting the matrix and see if that

Hi community!
I've been failing to use Quat4f in a robust manner now several times. I just
want to do an interpolation of orientation. Most of the time, the results

totally distorted results.

Title: GeometryUpdater
I am not sure I fully understand the purpose of the GeometryUpdater.
If I modiy the GeometryArrays on Shape nodes, I can either recreate,
or modify existing ones. Either way, I usually just detach the branch,
and reattach it after modification/creation.

Greg,
I'm doing approximately what you describe. For each object that moves, I test
for collisions by testing a number of pick segments that represent lines between
points on the surface of the moving object in its old and new positions.
Choosing 'enough' pick rays is the delicate part. I'm using
I have looked at the code you sent me, and I was able to make the models
spin. There are several wrong doings in your code.
1. First of all, you should set the "scheduling bounds" of the rotation
interpolator and not the bounds!!! That's why it's not spinning right from
the begining.
2. It's good
