论文摘要
森林环境的模拟具有从娱乐和艺术创作到商业和科学建模的应用。由于森林中的独特特征和照明，因此需要一个森林特定的模拟器，但是许多当前的森林模拟器都是专有或高度量身定制的特定应用程序。在这里，我们回顾了程序生成的几个领域和针对森林生成的特定领域，并利用它来创建一种广义的开源工具来生成和渲染互动，逼真的森林场景。该系统使用专门的L系统来生成使用生态系统仿真算法分布的树。最终的场景是使用递延渲染管道（具有实时叶片透明度和后处理照明效应的Blinn-Phong Lighting模型）渲染的。结果是一个在高自然现实主义和视觉吸引力之间达到平衡的系统，适用于培训计算机视觉算法的任务，用于自主机器人和视觉媒体的生成。
Simulation of forest environments has applications from entertainment and art creation to commercial and scientific modelling. Due to the unique features and lighting in forests, a forest-specific simulator is desirable, however many current forest simulators are proprietary or highly tailored to a particular application. Here we review several areas of procedural generation and rendering specific to forest generation, and utilise this to create a generalised, open-source tool for generating and rendering interactive, realistic forest scenes. The system uses specialised L-systems to generate trees which are distributed using an ecosystem simulation algorithm. The resulting scene is rendered using a deferred rendering pipeline, a Blinn-Phong lighting model with real-time leaf transparency and post-processing lighting effects. The result is a system that achieves a balance between high natural realism and visual appeal, suitable for tasks including training computer vision algorithms for autonomous robots and visual media generation.
