摘要
针对自然界中真实叶片纹理细节的不规则性和随机性,该文借助粒子系统思想提出了一种基于能量模型的叶片纹理构造算法。计算机仿真结果表明它比通常的纹理贴图法有更好的随机性和立体感,非常适用于描述叶片纹理这种细节比较复杂但又存在内在规律的事物。
Aiming at the scrambling and randomicity of real leaves in nature,this article advances a leaf texture constructing algorithm based on the energy model from the conception of particle system.The result of computer emulation shows that the algorithm has better randomicity and appearance of third dimension than normal texture algorithms,and it is very suitable to describe the objects with complex details and intrinsic rules such as leaf texture.
