Not sure if this will help, but the term "knot" is used
extensively in Java 3D interpolators. Read the javadoc for
PathInterpolator.

> Enumeration en = tg.getAllChildren();
> while(en.hasMoreElements()) {
> Object o = en.nextElement();
> if (o instanceof KBSplinePathInterpolator) {
> KBSplinePathInterpolator k = (KBSplinePathInterpolator)o;
> for (int i = 0; i < k.getArrayLength(); i++) {
> k.getKeyFrame(i).debugPrint("" + i); }

> 1. KBSplinePathInterpolator.getArrayLength() seems to return 1 too much (i'm
tired)
> 2. The only value which changes in an animation is "knot"
>
> What is a "knot"??? How does it translate to a Transform3D or something else?
I've
