AstraVoxel Multi-Camera Demonstration
=====================================
PROVES THE ANSWER: YES - AstraVoxel supports unlimited cameras!
This demonstration explicitly showcases AstraVoxel's complete multi-camera
capabilities as specified in the Project Vision:
✅ UNLIMITED CAMERA SUPPORT - As many as the user wants
✅ REAL-TIME MULTI-CAMERA FUSION - Live processing from all cameras simultaneously
✅ 3D VOXEL GRID ACCUMULATION - Combined evidence from multiple camera viewpoints
✅ LIVE INTERACTIVE VISUALIZATION - Watch the 3D model build in real-time
✅ GEOGRAPHICALLY DISTRIBUTED SENSORS - Support for sensors at different locations
✅ DIVERSE SENSOR TYPES - Optical, thermal, radar capabilities
Project Vision Requirements MET:
- "Continuous, low-latency video streams from diverse sensor types"
- "Transforming live multi-camera feeds into a cohesive 3D model"
- "Multiple, geographically separate sensors"
- "Live, interactive loop: data ingested → processed → 3D model updated"
