Battlefront.com and Akella have announced that the dedicated developer diary blog for their upcoming PT Boats: Knights of the Sea naval simulation game is now updated with a new entry detailing the water physics. The surface of water corresponds to a conditional plane with two animated altitude maps laid upon its geometrical grid. One of these maps is used to represent the waves, and the other one is used to model the ripple on the surface of water. It activates when the camera approaches the water surface closely.
