Signal in the Dark - Three.js simulator for searchlight vs beacon strategies

Show HN: Find someone in the dark – light them or light yourself? (Three.js)

Signal in the Dark is an interactive Three.js experiment that visualizes two distinct search-and-rescue strategies in a 3D environment. Users can compare the effectiveness of a rescuer actively sweeping a searchlight versus a missing person approaching a stationary beacon. The simulator allows testing various scenarios, such as mobile hikers, injured individuals, or dense forests, to see how line-of-sight and movement impact detection. Built as a conceptual toy model, it isolates key variables to offer intuitive insights into visibility dynamics without complex real-world constraints.
