森林公园景观绿化演变视觉模拟方法

由于森林公园景观人为干预较少,其绿化演变过程的随机性较强,视觉模拟过程中缺少对森林景观中细节细分的过程,导致森林层次区域的模拟失真。为解决这种问题,提高森林公园景观绿化演变视觉模拟效果,提出一种基于智能算法的模拟方法,即运用中点位移法与连续随机增加法对森林景观图像去褶皱,利用多细节层次法生成原始森林景观三角形网格,利用分形技术递归细分该森林景观的三角形网格,视觉过渡不同细节层次区域,经视觉渲染后最终获得景观绿化演变视觉模拟结果。测试实验表明,该方法模拟的森林公园景观绿化演变图像较为清晰、逼真。

Design of Visual Simulation Method for Forest ParkLandscape Greening Evolution

Due to less human intervention in the forest park landscape, the randomness of its greening evolutionprocess is strong, and the lack of detailed segmentation of the forest landscape in the visual simulationprocess leads to the simulation distortion of the forest level area. In order to solve this problem andimprove the visual simulation effect of forest park landscape greening evolution, this paper proposed a visualsimulation method of forest park landscape greening evolution based on intelligent algorithm. The forestimage was deconstructed by the midpoint displacement method and the continuous random increasemethod. The original forest landscape triangle mesh was generated by using the multi level of detail method,and the fractal technology was used to recursively subdivide the triangle mesh of the forest landscapeto visually transition the regions with different levels of detail. The visual simulation results of the forestpark landscape greening evolution with realistic effects were finally obtained after visual rendering. Thetest results showed that the forest park landscape greening evolution simulated by this method was clearer and more realistic.
