Hello,

I post a new liquid animation. It's again a ball falling in a tank of water.
The sphere is a little bit less dense then in the previous post.

On the simulation side, I added the handling of the rotation during the
simulation. I also changed the fluid -> object interaction : in the
previous simulations, only a force perpendicular to the surface was applied
on the object (proportional the the fluid pressure), resulting in no
rotation change in the case of a sphere. Now, I add a tangential force
proportional to the speed difference between the object and the water.

For the rendering, the object is no more an isosurface but a mesh. It makes
the object more regular than in the previous post. Moreover, I applied a
wood texture on it in order to visualize the sphere rotation.

Comments are welcome.

The video is MPEG1 encoded.

Regards,
Fidos.
