- Implement orbit camera with smooth zoom and collision detection
- Add 50° slope limiting with sliding (prevents mountain climbing)
- Add first-person mode that hides player model and weapons
- Add floor clearance check to prevent camera clipping through ground
- Improve WMO wall collision with proper height range checks
- Add two-sided floor collision detection for WMO geometry
- Increase M2 render distance slightly for better visibility
- Add loading screen system with stb_image for JPEG loading
- Two loading screen images (orc and dwarf) randomly selected
- Display loading screen while terrain data loads
- Cache WMO inverse matrices to reduce per-frame computation
- Stub WMO liquid rendering (needs coordinate system fix)
- Update spawn point to Stormwind Trade District
- Spawn position changed to (-9080, -100, 100) which is on actual terrain
- The terrain mesh uses WoW coordinates from ADT files directly
- Camera/spawn position must use same coordinate system as terrain
- Cleaned up getHeightAt comments to clarify coordinate system
- Removed debug logging from WMO floor detection
- Increase WMO render distance from 1500 to 3000 units for better city loading
- Increase M2 render distance from 500 to 1000 units
- Increase terrain load radius from 4 to 6 tiles (~3200 units)
- Add raycast-based camera collision that zooms in when obstructed by walls/objects
- Move spawn point outside chapel to road near Stormwind gate
- Add ground height smoothing to prevent stumbling on uneven terrain
