From the README

一个纯程序化生成的「樱花空岛」3D 场景,单文件网页,用 Three.js 从零建模——没有任何外部模型、贴图或音效素材,所有几何体、贴图、云层、星空、月面都是在运行时算出来的。

A procedurally generated floating sakura island, built entirely in code with Three.js. No external models, textures or audio assets — every mesh, texture, cloud, star and crater is generated at runtime.

空岛:非规则轮廓的径向网格地形 + 分层岩体,地表用 Canvas 现场绘制的「厚涂」贴图(同一樱花色系的六档纯色、三层笔触,并复用为 bumpMap 做出颜料堆叠感). 植被:一簇六叶的自定义草簇几何(两万多个实例,顶点着色器风场);单色小花;递归分叉的樱花树(枝干沿曲线收分,叶团用球面法线的贴图卡片);垂枝樱;持续飘落的花瓣。 做旧:木纹与石纹程序贴图 + 世界高度积垢着色器(墙脚越脏、带竖向水痕与霉斑). 副岛与魔法锁链:四座小岛按 270° 均分环绕,每座都有樱树;锁链以双螺旋缠满主岛岩体,链节为实例化环形,链芯是带流动脉冲与符文带的加色管线,另有 460 颗沿链流动的火花。
