The pure, deterministic radar model — range + detection cone + lock acquisition, Babylon-free (plain {x, y, z}, time only via dt, no Date.now/Math.random), so it unit-tests headless like fly-by-wire / world-store. b3d-radar.ts bridges it to the scene (enumerates RadarBlips, supplies the platform pose, plots the HUD).

A Radar detects contacts within range · profile AND inside its cone (dot of the platform's forward with the bearing to the contact ≥ coneDot; ±90° → coneDot 0). Detected, lockable contacts build a lock over lockTime seconds; up to maxLocks of the nearest ones hold locks at once. Losing detection decays the lock back down.

Example

The pure, deterministic model — b3d-radar bridges it to the scene (blips, HUD traces, homing-missile locks). Direct use is a Radar you step each tick:

import { Radar } from 'tosijs-3d'
// range + a detection cone + lock acquire/decay, seeded and Babylon-free — feed it blip positions
// each dt and read its tracks / nearest lock. See <tosi-b3d-radar> for the wired-up version.
