Don't eat me

I'm just starting out in java3D, and am now at the point that I'd like to start moving shapes around. However, the methods given in the tutorials I've read seem suspect.

PositionInterpolators and PositionPathInterpolators...
They're behaviors. Behaviors have bounding regions. So, everything that moves around the universe will carry the extra overhead of checking the interpolator's bounding region.

So, my question is, is there a way of disabling the bounds on a behavior, or is there an alternative to interpolators. If anyone knows of any websites that discuss this in greater depth, it'd be greatly appreciated.

Thanks.

behavior is activated once its bounding region is intersected  - if you dont supply bounds it will never start doing its job - not much one can do about that ... having said that you could create your own thread and inside implement whatever you need - that might be preferable way to for some tasks since behaviors are not well timed....but if you decide to do it using threads then you - your thread - will be responsible for checking when to get active ..... so certain amount of overhead will still be present .....

If you make the bounds on a Behavior "global", then it should drastically reduce the bounds-checking time.

Use a BoundingSphere with a radius of Double.MAX_VALUE.
