论文摘要
程序地形生成是使用计算机程序或程序生成数字代表地形的过程，几乎没有人类的指导。本文提出了一种基于河流侵蚀的图表表示程序性地形生成算法，该算法对现有算法进行了几种新的改进。也就是说，使用具有两种局部定义约束强度的高度约束图；通过降雨水平来指定逼真的侵蚀强度的能力；以及雕刻现实峡谷的能力。这些新颖性使其能够通过集成其他参数和仿真过程来产生更多样化和现实的地形，同时由于这些新参数和过程的性质和直觉，在更快的速度上，为地形设计师提供了更大的灵活性和易用性。本文还回顾了一些用于评估地形发电机的常见指标，并提出了一个全新的指标，该指标有助于更全面的评估。
Procedural terrain generation is the process of generating a digital representation of terrain using a computer program or procedure, with little to no human guidance. This paper proposes a procedural terrain generation algorithm based on a graph representation of fluvial erosion that offers several novel improvements over existing algorithms. Namely, the use of a height constraint map with two types of locally defined constraint strengths; the ability to specify a realistic erosion strength via level of rainfall; and the ability to carve realistic gorges. These novelties allow it to generate more varied and realistic terrain by integrating additional parameters and simulation processes, while being faster and offering more flexibility and ease of use to terrain designers due to the nature and intuitiveness of these new parameters and processes. This paper additionally reviews some common metrics used to evaluate terrain generators, and suggests a completely new one that contributes to a more holistic evaluation.
