b3d-radar-blip

Tags something as detectable on radar — a target, a landmark, a waypoint. It has no geometry of its own; it just contributes a blip that a radar platform (the aircraft HUD) plots. Two ways to place one:

Nested in a target (<tosi-b3d-destroyable>, a vehicle, any element with a mesh) — the blip follows that mesh, so a moving target moves on radar for free.
Directly in the scene — a static blip at its own x/y/z (waypoints, fixed landmarks). It rides the floating origin.

The live demo lives on b3d-radar — a blip only means something to a sensor, so one scene shows both: a sweeping mast, three blips of different faction and profile, and a readout of what is detected and what is locked. Duplicating it here would be two scenes to keep in step and one idea.

Attributes

Attribute	Default	Description
`profile`	`1`	Detectability: `1` = seen at the platform's nominal radar range, `2` = out to 2×, `0.05` = very stealthy; negative = always detectable (e.g. waypoints).
`faction`	`'neutral'`	`friendly` / `neutral` / `hostile` / `waypoint` — drives the radar-trace colour.
`x`,`y`,`z`	`0`	World position when standalone (ignored while following a target's mesh).

import { b3d, b3dRadarBlip, b3dDestroyable } from 'tosijs-3d'

// A hostile target that shows on radar (blip follows the cube):
b3dDestroyable({ x: 0, y: 1, z: 40, capacity: 6 },
  b3dRadarBlip({ faction: 'hostile', profile: 1 }))

// A waypoint: no mesh, always detectable, shown as a waypoint trace:
b3dRadarBlip({ faction: 'waypoint', profile: -1, x: 0, y: 0, z: 200 })
