# ClusterLOD C# Translation — Work Summary

## ✅ Completed Work

I've successfully translated the C++ `clusterlod` library to C# using your GhostEngine infrastructure:

### Files Created

1. **ClodConfig.cs** — Configuration struct with fields (`camelCase`) and properties (`PascalCase`)
2. **ClodMesh.cs** — Unsafe mesh data structure (pointers for high-performance access)
3. **ClodBounds.cs** — Bounds representation with center, radius, and error
4. **ClodBuilder.cs** — Main API entry point with full `clodBuild` implementation
5. **ClodInternal.cs** — Clusterization using `meshopt_buildMeshlets*` bindings
6. **ClodInternal_Partition.cs** — Spatial partitioning via `meshopt_partitionClusters`
7. **ClodInternal_Boundary.cs** — Boundary locking to prevent mesh seams
8. **ClodBoundsHelper.cs** — Bounds computation and merging
9. **ClodSimplify.cs** — Full simplification pipeline (permissive + sloppy fallbacks)
10. **AGENT_GUIDELINES.md** — Your naming conventions and architecture guide

### Features Implemented

✅ High-performance memory via `UnsafeList<T>` from `Misaki.HighPerformance`  
✅ Full cluster LOD hierarchy generation  
✅ Attribute-aware simplification  
✅ Error monotonicity tracking  
✅ Boundary preservation across simplification  
✅ Proper allocator handling and cleanup  
✅ Edge-length error limiting  
✅ Fallback simplification (permissive & sloppy modes)  
✅ C# naming conventions (fields camelCase, props PascalCase, consts UPPER_SNAKE_CASE)

### Changes to Native Bindings

- Renamed `NvttApi` → `MeshOptApi` in `meshopt.json` config
- Re-ran code generator to produce `MeshOptApi.nativegen.cs` and mesh-related wrapper files

### Local Commits

```
301a6d1 feat: translate clusterlod to C# and restructure to Ghost.Graphics.Meshlet
```

## 📤 Next Steps (You)

The commit is ready locally. To push and create a PR:

```bash
cd projects/GhostEngine
git push origin develop
```

Then create a PR from `Julian/GhostEngine:develop` → `Misaki/GhostEngine:develop`.

## 🎯 What's Ready for Testing

- Full clusterization pipeline
- Spatial/flex meshlet building
- Simplification with all fallback modes
- Bounds computation and hierarchy tracking
- Ready to integrate with your graphics pipeline

Let me know if you'd like me to refine anything or add documentation!
