Abstract: Procedural content generation, as an aid to digital content production, has been increasingly applied to games, architectural design, digital entertainment and other fields, and greatly improves the efficiency of digital content production. Wave function collapse（WFC） as a procedural content generation algorithm, is a grid-based solution with association rules. With the help of the Unity3d engine, this paper proposes an improved method of slot subdivision based on the WFC algorithm. Slot subdivision method works on single-level scene model generation, provides constraint-rule based orderly refinement of the scene. Assisted with certain interactive functions, slot subdivision method creates a fine-tuned, credible and controllable scene environment with details.

Key words: procedural content generation, wave function collapse（WFC）, slot subdivision, constraint rules, interactive scene generation

摘要： 程序化内容生成作为一种数字化内容生产的辅助手段，已经越来越多地应用到了游戏、建筑设计、数字娱乐等领域，极大提高了数字内容的生产效率。作为程序化内容生成算法的一种，波函数坍缩算法（wave function collapse，WFC）提出了一种网格化的基于关联规则的解决方案。借助Unity3d平台，以WFC算法为基础，提出了插槽多维细分的改进方法，该方法能够在单层次的场景模型生成基础上，基于规则有序进行场景的细化，并辅助以一定的交互功能，最终创建出精细、可信且具有细节可控性的场景环境。
