The VR config panel was extending 55cm below the handle bar due to
incorrect positioning calculation.
Problem:
- Panel dimensions: 2m wide × 1.5m tall
- Panel was positioned at y=0.2m above handle center
- This placed panel bottom at y=-0.55m (55cm BELOW handle)
- Panel overflowed significantly below the handle bar
Solution:
- Calculate proper position based on panel height
- Position panel center at y=0.8m (0.75m half-height + 0.05m gap)
- Panel bottom now sits 5cm above handle, matching toolbox appearance
- Add 0.6x scaling to match toolbox compact size (1.2m×0.9m actual)
Result:
- Panel bottom aligns just above handle bar
- Consistent visual relationship with toolbox
- Comfortable viewing distance and ergonomics in VR

Label Positioning Fixes:
- Fix labels accounting for mesh scaling using maximumWorld coordinates
- Labels now properly positioned on scaled objects (spheres, boxes, etc.)
- Restore world→local coordinate transformation in updateLabelPosition
Billboard Mode Implementation:
- Add configurable label rendering modes: fixed, billboard, dynamic, distance-based
- Implement billboard mode (labels always face camera using BILLBOARDMODE_Y)
- Add label rendering mode to AppConfig with default 'billboard'
- Add UI selector in ConfigModal for label rendering mode
- Observable pattern updates all existing labels when mode changes
XR Entry Positioning Fix:
- Synchronize desktop camera position to platform before entering XR
- Transfer camera world position and rotation to prevent scene shift
- Reset physics velocity on XR entry to prevent drift
- Add debug logging for position synchronization
Config System Architecture Fix:
- Create singleton appConfigInstance to ensure single source of truth
- Update DiagramObject to use singleton instead of creating instances
- Update DiagramManager to use singleton
- Fix ConfigModal to update AppConfig directly (was only updating legacy config)
- ConfigModal now triggers Observable notifications via appConfigInstance setters
- Maintain legacy config for backward compatibility
- Fixes issue where label rendering mode changes didn't take effect
