# CORTEX ENGINE — VULKAN RENDERER IMPLEMENTATION PLAN

## Status: COMPLETE

All phases implemented. See `CORTEX_ENGINE_ARCHITECTURE.md` for current architecture.

## Completed Phases

1. ✅ Vulkan P/Invoke foundation (Vulkan 1.3, dynamic rendering, sync2)
2. ✅ Push constants (model matrix)
3. ✅ UBO + descriptor sets (SceneUBO with multi-light data)
4. ✅ Index buffer + OBJ loading
5. ✅ Depth buffer (D32_SFLOAT)
6. ✅ Face normal computation
7. ✅ FreeFlyCameraController (WASD + mouse look)
8. ✅ Projection matrix fix (Y-flip + no row_major)
9. ✅ ECS scene (mesh cache, per-entity model matrix)
10. ✅ PBR shading (Cook-Torrance, ACES tonemapping)
11. ✅ Jolt physics (gravity, collision, floor)
12. ✅ ImGui debug overlay
13. ✅ AI/MCP (7 tools, HTTP SSE)
14. ✅ Cubemap shadow mapping (omnidirectional, 6 faces per light)
15. ✅ Multi-light system (cubemap array, per-light shadows)
16. ✅ Soft shadows (16-tap Poisson disk PCF)
17. ✅ Shadow parameters ImGui panel
18. ✅ Video recording (FFmpeg pipe)
19. ✅ Adjustable ambient lighting
20. ✅ Physics pause/resume + scene reset
21. ✅ 227 xUnit tests
