摘要

本文研究了基于递归细分的分形生成的三种方法，两种现有方法和一种新的方法。发现现有的两种方法都有缺陷，而新方法没有。提出了一种高度域绘制的并行处理算法，该算法既精确又均匀地分配了处理器之间的负载。描述了一种高度场的“扇形追踪”方法，以实现对水面反射的真实模拟。

The definition and rendering of terrain maps

This paper examines three methods, two existing and one new, for the generation of fractals based on recursive subdivision. Both existing methods are found to have defects, which are not present in the new method. A parallel processing algorithm is proposed for the rendering of height fields which is exact and distributes the load evenly between the processors. A method is described for the 'fan-tracing' of height fields to allow the realistic simulation of water reflections.
