code-built-3d SKILL.md skillB
code-built-3d from majiayu000/spellbook is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

用代码从零件搭 3D 场景并能反过来拆开：每个物件是一个往 Assembly 里加零件的函数（盒子、圆柱、球、线），渲染成技术插画（白灰三档面、细黑描边、白雾），正交等距相机在镜头之间连续运镜，外壳可以降下去露出内部，选中的部分能爆炸成零件并列出零件清单，场景按块无限生成。零图片、零外部资源，three.js 已内置。演示是「无尽楼」：向上无尽的公寓楼，电梯一直往上走，点任意一层进去看、拆开。当用户说「用代码搭一个 3D 场景」「等距 3D 城市」「做成 Train of Thoughts 那种」「全程代码生成不要图片」「能剖开 / 去壳 / 爆炸的 3D」「无限生成的场景」「three.js 做构造」时使用。只在明确请求时触发，忽略顺带提及。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 代码搭 3D 场景 这个 skill 做两件事：从零件把一个东西搭出来，再把它拆开。两件事用同一套零件数据。 | 环节 | 怎么做 | 在哪 | |---|---|---| | 零件 | 每个物件是一个函数，往 `Assembly` 里加 `box / cyl / cone / ball / line`。每个零件带名字、角色（`shell` 是能降下去的外壳）、尺寸，可选爆炸方向 | `assets/kit.js` 的 `Assembly` | | 画法 | 面的明暗按朝向分三档（顶面最亮，朝镜头的两面依次暗一档），每条边描细黑线；离焦点越远（竖向距离或深度）越融进白色 | `createLook()`，一个着色器 | | 镜头 | 正交相机。镜头 = 目标点、缩放、方位角、仰角，换镜头时用 smootherstep 连续过渡，缩放按对数插值。不硬切 | `Director` | | 去壳 | 外壳按 y 方向缩到 0，像墙沉进地板。看房间时，上面的楼层整体抬起 | `setShell()`，demo 里的 `LIFT` | | 拆开 | 把选中的部分改成逐零件建模，零件分层往上升，水平方向不超出给定范围；`manifest()` 给出零件清单（名字、尺寸、位置） | `exploder()`、`Assembly.manifest()` | | 交互 | 悬停显示包围框和标签，点击切到对应镜头；DOM 气泡钉在 3D 点上，被雾吞掉时自动隐藏 | `picker()`、`outline()`、`labels()` | | 无限 | 以一个移动的坐标为中心，只保留前后若干块，出范围的块回收；同一个种子永远生成同一座城 | `streamer()`、`rng(seed)` | ## 文件 - `assets/kit.js`：引擎（ES 模块）。 - `assets/tower.js`：演示用的零件库，包括人、椅子、桌子、灯、植物、空调外机、7 种房间、楼层、电梯轿厢、邻楼分段（5 种立面）、连廊、电缆。 - `assets/demo.html`：无尽楼。一份 import map 指向 `vendor/`。 - `assets/vendor/`：three.js r184 的 `three.module.min.js`、`three.core.min.js`、`BufferGeometryUtils.js`，以及 MIT 许可证 `THREE-LICENSE`。不依赖 CDN。 - `scripts/serve.mjs`：静态服务器。ES 模块不能从 `file://` 加载，必须用它打开。 - `scripts/check.mjs`：验收脚本，通过页面上的 `window.__scene` 驱动。 本地打开演示： ```bash …

How to install
mdr add majiayu000/spellbook/code-built-3d@sha256:03489f377115609dThe line at the top of this page pins the label git:20261102.47f8439, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
