Performance Notes
Use BufferGeometry for large models
Limit draw calls by merging meshes
Reduce texture resolution if needed
Use frustum culling
Reuse materials and geometries
Security Notes
Runs sandboxed in browser
No unsafe memory access
Avoid loading untrusted assets
WebGL shaders validated by browser
No direct access to GPU beyond WebGL API
Monitoring Analytics
Use Stats.js for FPS monitoring
Profile renderer for bottlenecks
Track texture and memory usage
Test performance across devices
Log animation timings and user interactions
Code Quality
Reuse materials and geometries
Keep scene graph organized
Use helper functions for repetitive tasks
Modularize shaders and animations
