3D game development principles. An agent skill from xenitV1/Antigravity-Workflows.
- Works in 7 steps: Rendering Pipeline → Shader Principles → 3D Physics → …
- Tasks that involve Game development

What it does
3D Games is an agent skill from xenitV1/Antigravity-Workflows. 3D game development principles. Rendering, shaders, physics, cameras.
Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Game Development, covering Game development and Shaders. The licence is MIT.
When your agent uses it
- Tasks that involve Game development
- Tasks that involve Shaders
Example prompts
- “/3d-games”
Requirements
- Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep
Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit f0a1fa7. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGlobGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
3D Games loads about 638 tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 227 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

3D Game Development
Principles for 3D game systems.
1. Rendering Pipeline
Stages
1. Vertex Processing → Transform geometry
2. Rasterization → Convert to pixels
3. Fragment Processing → Color pixels
4. Output → To screenOptimization Principles
| Technique | Purpose |
|---|---|
| Frustum culling | Don't render off-screen |
| Occlusion culling | Don't render hidden |
| LOD | Less detail at distance |
| Batching | Combine draw calls |
2. Shader Principles
Shader Types
| Type | Purpose |
|---|---|
| Vertex | Position, normals |
| Fragment/Pixel | Color, lighting |
| Compute | General computation |
When to Write Custom Shaders
- Special effects (water, fire, portals)
- Stylized rendering (toon, sketch)
- Performance optimization
- Unique visual identity
3. 3D Physics
Collision Shapes
| Shape | Use Case |
|---|---|
| Box | Buildings, crates |
| Sphere | Balls, quick checks |
| Capsule | Characters |
| Mesh | Terrain (expensive) |
Principles
- Simple colliders, complex visuals
- Layer-based filtering
- Raycasting for line-of-sight
4. Camera Systems
Camera Types
| Type | Use |
|---|---|
| Third-person | Action, adventure |
| First-person | Immersive, FPS |
| Isometric | Strategy, RPG |
| Orbital | Inspection, editors |
Camera Feel
- Smooth following (lerp)
- Collision avoidance
- Look-ahead for movement
- FOV changes for speed
5. Lighting
Light Types
| Type | Use |
|---|---|
| Directional | Sun, moon |
| Point | Lamps, torches |
| Spot | Flashlight, stage |
| Ambient | Base illumination |
Performance Consideration
- Real-time shadows are expensive
- Bake when possible
- Shadow cascades for large worlds
6. Level of Detail (LOD)
LOD Strategy
| Distance | Model |
|---|---|
| Near | Full detail |
| Medium | 50% triangles |
| Far | 25% or billboard |
7. Anti-Patterns
| ❌ Don't | ✅ Do |
|---|---|
| Mesh colliders everywhere | Simple shapes |
| Real-time shadows on mobile | Baked or blob shadows |
| One LOD for all distances | Distance-based LOD |
| Unoptimized shaders | Profile and simplify |
Remember: 3D is about illusion. Create the impression of detail, not the detail itself.
