how to simulate a floating object?

    I just discovered the @shape dynamicmesh example patch, and thought it would be the best tool to simulate a buoy floating on a water surface. Can I make a jit.phys.body object directly interact with this surface? ( it involves to allow overlapping between the dynamic mesh and the buoy) If it is not the right solution, Should I evaluate the normal vector at a given point of the surface to make my objet follow its movements? I saw that jit.anim.node had a direction attribute but I don't know how to get it from a precise point of the dynamic mesh...

      i would us phys.ghost for this:

      thank you for pointing me the phys.ghost objet. I definitely have to study it Actually, my floating object was a shortcut for finding the normal vector at a given point of the water surface. The normal orientation will trigger some sound events and variations. the floating objects with the ghost solution will only fluctuate on their y axis. and jit.bfg is perfect for water surface simulation. Here is what I tried to achieve. Is there a way to get and draw the normal vector? I may not have to use a "buoy" for that. I have read I can get the normal matrix thanks to @matrixoutput from a gridshape, is it a solution to study?
