feat: implement LOD hysteresis to prevent model popping#1310
Merged
Conversation
Add LOD hysteresis system to prevent flickering when entities are near LOD distance boundaries. Uses a 10% margin (configurable via lodHysteresis setting) to create a "dead zone" around thresholds. Changes: - AssetManager: Add getBestLODWithHysteresis() function - UnitRenderer: Track per-entity LOD, use hysteresis in selection - BuildingRenderer: Same implementation for buildings - UnifiedCullingCompute: Add hysteresis to CPU fallback path - CullingService: Clean up LOD tracking on entity unregister - uiStore: Add lodHysteresis graphics setting (default 0.1) - rendering.md: Document the LOD hysteresis system With 10% hysteresis: - LOD0→LOD1 switches at 55 units (50 * 1.10) - LOD1→LOD0 switches at 45 units (50 * 0.90) - LOD1→LOD2 switches at 132 units (120 * 1.10) - LOD2→LOD1 switches at 108 units (120 * 0.90) https://claude.ai/code/session_01KbKNtVm9MU6RxTPZJGsZdg
