Research On Modeling Of Curved Wave

Virtual Reality is a new technology developed recently, which integrates many information technology and gives us a strong support in building and roaming in virtual world. Virtual Reality has been used in many fields. And meanwhile, Digital Ocean technology has been well developed, which provide an intuitionistic and convenient approach to comprehend the ocean. There are some specialists thought that virtual ocean possess at least three merits: vindicating ocean rights; managing ocean environment; managing ocean resources. It should be useful that use the virtual reality to manage the ocean information.The wave modeling is a very important field of virtual ocean scene, usually, people need fast render speed, meanwhile, the scene should be as really as possible. The traditional wave models either too complicate to quick rendering, or use simple model that can't demonstrate real ocean scene. This paper present a breaking wave model and generate an efficient and really breaking wave, our model consider the factor of efficiency and facticity, perfect solved this problem.Recast the Fournier model which is the basic model can achieve the breaking effect. Because the basis model can render the relatively calm ocean, but it's difficult to exhibit the breaking wave, we can get the breaking effect through recast the specific segment of the wave. In our paper, we employ the Bezier curve to recast the breaking part, and depart the wave period to three stages: curve, surge and retreat. Compute every stage using corresponding parameterized Bezier curve, we can control the waveform by change the control point of the Bezier curve, and we could change the control point with the time elapsing, so we could get the cartoon effection. At last, we use particle system to render the spray and foam.This method can solve the smooth transformation of the waveform from deep water to shallow water. Meanwhile, the render result of the advanced algorithm was...
