When you have a simple bezier curve with two points and two tangents, what's the easiest way to rig this in Houdini?. I am looking for something that can be hand animated.

In xsi I would have normally add a cluster center to the end points, and to the tangent points. I would have then parent the tangent point null clusters to the end ones, so they would follow.

What is the houdini approach?

I really need to review the rigging side of houdini, any good resources? or where to start?

Thanks!
