We have generated three dimensional wake waves by using computer graphics. A wake wave is a kind of wave made by things moving on or through water: objects such as ships, surfboards and animals like waterfowls or ducks. It is known that wake waves can be represented by combining Kelvin waves; however, there has only been studies on two dimensional representation and no study on three dimensional. Therefore, this paper describes how to generate three dimensional wake waves like those made by a waterfowl. To make three dimensional wake waves, the phase difference of Kelvin waves and the amplitude of wake waves are both necessary. In this study, we decided these parameters by measuring a real photograph of a waterfowl and by some ship references. Finally, we have generated three dimensional wake waves by using computer graphics and confirmed that the proposed method can generate wake waves similar to real ones by comparing the generated CG images with real photographs.
