摘要:
为真实地模拟自然界的森林景观,在利用分形递归算法构建参数化三维树木模型的基础上,结合OpenGL函数,将纹理映射、Alpha测试和地面阴影应用到树木的真实感绘制中.并在算法中引入随机数,实现大小不同、形态各异的树木生成.绘制时,根据视点距离的远近,调整场景的精细程度,以符合视觉效果,且加快了图形生成速度.以此方法构造森林,可改变观察者的视点位置,实现对森林景观的实时模拟.
Abstract:
To simulate the forest scenery of nature truly,a method of real-time simulation based on fractal recursion trees is presented in this paper.By constructing parameterized 3D trees model using recursion algorithm,and combi-ning OpenGL function,texture-mapping,Alpha testing and ground shadow are applied to realistic rendering of trees.In addition,random numbers are introduced into algorithm,which generated trees that have different size and various shapes.According to the distance from view point,fine degree o...
