RealFlow's Hybrido technology is perfectly suited to the creation of large amounts of water, such as floods, or ocean surfaces. You start with the so-called core fluid to simulate the fluid's expansion and the main splashes. Once you are happy with the behaviour and look of the core fluid you add more and more details: surface ripples and waves, small splashes, foam, and mist. All these elements are simulated in separate passes. The main idea is to use the already simulated parts and data, and virtually create a new level on top of the existing simulation.
The advantage of this split workflow is that you are able to focus on just one element of the simulation and fine-tune its final look while the already existing parts are left untouched. This way it is also possible to simulate some parts over a network. This applies for the creation of all secondary elements and meshes.
One of these elements is the core fluid's ocean statistical spectrum model, also known as displacement, or just "OSS". The displacement is applied to the core fluid's surface and creates all the small waves you can see on a calm ocean. RealFlow provides two fundamental methods for the creation of these waves: the first method uses a sequence of displacement maps. These maps can be loaded into your 3D program and used with the RealFlow RenderKit or any other material.
