摘要
该文对雨滴水波的仿真包括雨滴在空中的运动状态和雨滴滴在水面上形成的水波的运动状态。在分析以往雨滴仿真技术存在缺点和不足的基础上,提出区域采样法和OpenGL技术对以往技术进行改善。具体做法是:①用该文推出的区域采样法水波数学模型替代以往复杂的水波数学模型,以减少计算量,降低编程难度;②用OpenGL的三角形图元及纹理坐标功能显示雨滴水波,用其纹理映射技术映射雨滴场景,实现三维真实感效果。从仿真的结果看,该算法和实现技术实现了对雨滴水波三维实时仿真并且提高真实感的目的,对提高影视制作及军事战场模拟中的雨滴水波的画面质量具有重要意义。
The simulation of raindrops and ripples includes motion of raindrops in the air and motion of ripples in the water in this paper. With an analysis of the shortcomings of former methods and technologies, the region segmentation and the OpenGL technology are presented. In detail, one is the former complicated formulas for ripples are substituted by formula about region segmentation with little calculation and easy program ; the other is raindrops and ripples are showed by triangles, texture coordinate, texture mapping in OpenGL with three - dimensional scene. The image of simulation shows that the purposes of simulating raindrops and ripples continuously and improving the fidelity of 3D simulation are attained by this way. And it is useful for improving the quality of raindrops＇ and ripples＇ image in movie and military simulation.
