doi:10.16182/j.cnki.joss.2015.06.016

Abstract

Abstract: The rendering of large-scale water area rain scene is one of the most challenging problems in computer graphics, and a method of rendering large-scale water area rain scene was proposed. By introducing the improved wave equation into the fuctuation of water surface and the interaction of water and raindrop, and incorporating the periodicity and wind tendency of FFT, an interactive fluctuation of water mathematical model in rainy days was established, based on which an interactive height map was rendered. Through the lighting rendering, the reflection effect and rain streaks were simulated. In order to enhance the efficiency, the level-of- detail techniques based on quad-tree were applied and the newest GPU acceleration was applied in order to take its full advantages. The method is efficient and achieves qualified refreshing frequency in real time scene rendering.

Key words: rain scene, FFT, wave equation, lighting, large-scale water area
