摘要
本文描述自然地形的侵蚀过程,导出由水力侵蚀和热力风化两个主要物理过程,经过大量次迭代反映其作用过程,建立了它们的计算模型,并显示其真实感图形。
This paper describes the erosion procedure of the natural terrain model,and deduces the
two main physical models or procedures by the hydraulic erosion and the thermal weathe
ring.The erosion procedure is reflected through a large number of iterative calculation,and
the gradual changing realistic graphics are displayed.
