Abstract:

For the problem that it is difficult to balance realism and realtime in modeling water,a new water effects simulation method based on Gerstner wave model is proposed.Firstly,random perturbations are added into the amplitude in order to make the fluctuations varied. Secondly, the superimposed Gerstner waves are divided into large waves and small waves, and it is more convenient to control waveform by changing the parameters of the different types of wave.Finally,the reflectivity and transparency are used to adapt to different environments and waters.The experimental results show that the new model not only presents a more realistic water effects,but also gets an ideal rendering speed.
