ClusterLOD C# Translation — Work Summary

✅ Completed Work

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

Files Created

ClodConfig.cs — Configuration struct with fields (camelCase) and properties (PascalCase)
ClodMesh.cs — Unsafe mesh data structure (pointers for high-performance access)
ClodBounds.cs — Bounds representation with center, radius, and error
ClodBuilder.cs — Main API entry point with full clodBuild implementation
ClodInternal.cs — Clusterization using meshopt_buildMeshlets* bindings
ClodInternal_Partition.cs — Spatial partitioning via meshopt_partitionClusters
ClodInternal_Boundary.cs — Boundary locking to prevent mesh seams
ClodBoundsHelper.cs — Bounds computation and merging
ClodSimplify.cs — Full simplification pipeline (permissive + sloppy fallbacks)
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

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:

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!
