摘要
提出了一种基于水平面的投影为参考起点,来生成一个很小的原始数据集,进一步构成多分辨率四边形网格,用以确定地形基座的形状。并用分形技术中的中点位移法及四边形边线插值细分方法对地形进行递归细分,从而生成自然的地形。模拟实验结果表明所提出的算法可以方便生成具有真实感、可控性的山脉地形,较好地解决了传统方法对生成地形的形状无法预测和控制以及不真实的问题。通过实验,对分形断面和分形地貌的模拟生成进行了可视化实验研究,结果证实了该方法的有效性和实用性。
Based on horizontal projection is proposed as a reference starting point to generate a very small amount of the origi-nal data set, further constitutes a Multiresolution quadrilateral mesh to determine the shape of topographic base. Using midpoint dis-placement method of fractal technology and its interpolation subdivision scheme for quadrilateral sideline terrain recursive subdivi-sion, thereby generating natural terrain. Experimental results show that the proposed algorithm can generate realistic, easily control-lable mountain terrain, a better solution to the traditional shape of the terrain on the build impossible to predict and control, and is not really an issue. Through experiments, fractal and fractal features of cross section to simulate a Visual experimental study was conducted, results confirmed the effectiveness and practicability of the method.
