Ocean Simulation

Overview

Ocean Simulation techniques can be classified into two main categories:

1. parametric/spectral methods that use oceanographicmodels

• describing the ocean surface directly in the spatial domain,use a height map computed as a sum of periodical functions, and animated with a simple phase difference, to represent the ocean surface.
• describing the ocean surface directly in the spectral domain,a wave spectrum to describe the surface in the spectral domain and a Fourier Transform to obtain its transformation in the spatial domain.
• hybrid the two

2. physically-based methods relying on NSE

Parameters and Control

• F1: increase ocean mesh
• F2: decrease ocean mesh
• Tab: switch between wireframe mode and solid mode
• F3: switch between render camera and obeserver camera
• F4: switch primitive topology between point and triangle list.
• F6: switch between GPU transform and CPU transform
