3d-games

3d-games is a skill for Claude Code, Codex from MisonL/Ling. It costs 32 tokens per session (970 once invoked), scanned A, original, MIT.

A guide to building 3D game systems, including how geometry becomes screen pixels, how shaders control appearance, how objects collide, and how cameras and lights work.

In plain words
What is it for?
Use it to plan rendering, write custom visual effects, choose collision shapes, design camera behavior, and structure lighting for a 3D game.
Why use it?
It helps explain the main technical choices behind a 3D game and ways to reduce unnecessary rendering work. It also separates simple collision shapes from detailed visual models.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

3d-games scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

3D 游戏开发

3D 游戏系统的原则。


1. 渲染管线(Rendering Pipeline)

阶段

1. Vertex Processing -> Transform geometry
2. Rasterization -> Convert to pixels
3. Fragment Processing -> Color pixels
4. Output -> To screen

优化原则

技术 用途
视锥裁剪(Frustum culling) 不渲染屏幕外区域
遮挡裁剪(Occlusion culling) 不渲染被遮挡部分
LOD(Level of Detail) 距离远时降低细节
批处理(Batching) 合并绘制调用

2. 着色器原则(Shader Principles)

着色器类型

类型 用途
顶点(Vertex) 位置、法线
片元/像素(Fragment/Pixel) 颜色、光照
计算(Compute) 通用计算

何时编写自定义着色器

  • 特效(水、火、传送门)
  • 风格化渲染(Toon、Sketch)
  • 性能优化
  • 独特视觉风格

3. 3D 物理(3D Physics)

碰撞体形状

形状 使用场景
盒体(Box) 建筑、箱体
球体(Sphere) 球、快速检测
胶囊体(Capsule) 角色
网格(Mesh) 地形(成本高)

原则

  • 碰撞体用简单形状,视觉用复杂模型
  • 分层过滤(Layer-based filtering)
  • 视线检测用射线(Raycasting)

4. 相机系统(Camera Systems)

相机类型

类型 用途
第三人称(Third-person) 动作、冒险
第一人称(First-person) 沉浸、FPS
等距(Isometric) 策略、RPG
轨道(Orbital) 检视、编辑器

相机手感

  • 平滑跟随(lerp)
  • 碰撞回避(Collision avoidance)
  • 运动前瞻(Look-ahead)
  • 用 FOV 变化体现速度

5. 光照(Lighting)

光源类型

类型 用途
方向光(Directional) 太阳、月亮
点光(Point) 灯、火把
聚光(Spot) 手电、舞台
环境光(Ambient) 基础照明

性能考量

  • 实时阴影开销大
  • 尽量烘焙(Bake)
  • 大场景用级联阴影(Shadow cascades)

6. 细节层级(LOD)

LOD 策略

距离 模型
全细节
50% 三角形
25% 或看板(billboard)

7. 反模式(Anti-Patterns)

[FAIL] 不要 [OK] 要做
到处使用网格碰撞体(Mesh colliders) 使用简单形状
移动端全开实时阴影 选择烘焙或投影(Blob)阴影
所有距离只用一个 LOD 按距离分级 LOD
未优化的着色器 性能分析(Profiling)后简化

提示: 3D 追求的是错觉,营造细节的印象,而非细节本身。

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

3d-games is a skill published in the GitHub repository MisonL/Ling (8 stars, last pushed 5mo ago), licensed MIT. It adds 32 tokens to every session and 970 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
