使用递归分形插值方法模拟真实感地貌景观

Model naturally-feeling sceneries of terrain by recursive fractal interpolation

采用随机中点位移法在三维空间中的扩展——方形四分法来插值,利用Python语言与OpenGL相结合,实现了对真实感地貌的模拟和显示,获得了较为逼真的效果,指出方形四分法的分形插值方法可以很方便地用在由规则格网采样的数字地形模型中来增强显示效果。

This article interpolated the values of a rectangle region using square-4 method, an extension of random middle-point moving method, and simulated and displayed the terrain of rectangle region with Python language and OpenGL library and got very beautiful scenery with great naturalness, Square-4 method can be used conveniently in digital terrain models generated with regular grid samples and can improve its display effectso
