基于分形参数的可控木纹纹理仿真

自然景物的模拟是计算机图形学中具有挑战性的研究方向之一.木纹纹理仿真是自然环境模拟中不可缺少的重要组成部分,但由于木纹纹理生成的复杂性和随机性,使得对其进行逼真仿真十分困难.在分析分形布朗运动以及随机中点位移法的基础上,讨论了中点位移法中各参数对分形曲线的影响,提出了一种非常简单的、基于参数可控的木纹纹理生成算法.仿真结果表明,方法具有快速、简单、高效,可控的特点,通过改变参数能较好地实现真实木纹纹理的仿真.

Simulation of Parameter-based Controllable Fractal-Wood Textures

Environment simulation has always been one of the most challenging tasks in computer graphics.Simulation of wood-texture is an indispensably important part of environment simulation.Because of the complexity and randomness of wood-texture,it is very difficult to simulate it realistically.Based on the deep study of the principles of fractional Brownian motion and the random mid-point displacement algorithm,the influences of different parameters on fractal curves are deduced.A method of parameter-based contro...
