Phase 5B Feature Demonstration
Demonstrates all 5 Phase 5B features:
1. Advanced Obstacle Patterns (maze, grid, circular, difficulty)
2. Shadow Quality Controls (4 presets)
3. Volumetric Lighting (god rays, fog)
4. Animation System (3 animation types)
5. Trigger Zones (3 zone shapes)
This example shows how to use all Phase 5B enhancements to create
rich, dynamic Gazebo simulation environments.
