object stick to animated surface

Hi there,

I have a loop animation of a water surface coming from Houdini and I am struggling to find a way to make objects to sit on the surface tangent of the water.

My aim is to animate those objects on a plane and then get them to sit on the water surface so that they can follow the waves.

Anybody can put me in the right direction?

Thanks

C.

Can you do a line trace down from just above the object to see where it hit the water, and then position the object there?
