The nice thing about Houdini is its versatility. Not only does it offer DOP solvers for fluids, RBDs and cloth, like many other applications, but it has some very specialized solvers, too. One of them being the ripple solver, that can be used to propagate waves across surfaces. And not only flat ones, like in this example!
In this tutorial I’ll show you how to set up a ripple solver and make a custom deformation VOP to deform the geo that is fed to the solver. By abusing the intended behaviour a bit we get around using complicated SOP solver setups and get the ball rolling, quickly.
