IronSight demonstrates a practical consumer application of multi-view 3D reconstruction—taking synchronized video from commodity devices (Ray-Bans, phones, action cameras) and converting it into a navigable 4D space where you can replay events from any angle. The value emerges in specific use cases (range training, tactical analysis, competitive shooting) where scenes have clear visual markers (targets) and controlled geometry. Multi-camera stitching gains immediate utility in these settings before it becomes mainstream. The real signal is the architecture itself: auto-syncing heterogeneous camera inputs and building a shared coordinate space. This unglamorous infrastructure layer enables everything from sports analysis to accident reconstruction without requiring specialized hardware or manual alignment.
