基于动态Impostor技术的树木快速绘制方法

树木快速绘制技术研究一直以来都是计算机图形绘制的一个热点领域,因为树木复杂的细节结构使其在绘制上存在着相当大的困难.提出了一种基于动态impostor技术的树木绘制方法,不仅可以快速地绘制树木,而且具有较高的真实感效果.该方法首先基于树木模型进行平面投影去创建impostor平面,然后将纹理映射到已经创建好的impostor平面上,最后通过绘制impostor纹理平面形成树木图像.当参考视点移动时,可以根据误差来决定是否动态更新impostor平面的内容.

Method on fast tree rendering based dynamic impostor technology

Research on fast tree rendering technology is a focus field of computer graphic rendering all the time,because complicate detail structure of tree makes it very difficult to rendering.A method on tree rendering based on dynamic impostor technology is presented,which not only can fast rendering tree,but also has highly realistic effect.This method firstly projects to the plane to create the plane of impostor based tree model,secondly maps the texture on the plane of impostor which has created,thirdly forms t...
