# Model Licenses

## aircraft.glb

- Name: ECAP detailed low-poly twin-engine aircraft
- Source: Generated locally for this project from simple geometric primitives
- Author: ECAP_Server project asset generation
- License: CC0-1.0
- Modified: Replaced the original minimal placeholder on 2026-07-24
- Notes: The model uses no external texture URL. It includes fuselage, canopy, swept main wings, tail wings, vertical stabilizer, engine nacelles and landing gear. The nose points along +X and the up axis is +Z for Cesium heading/pitch/roll orientation.

## aircraft-*.glb typed aircraft models

- Name: ECAP typed aircraft model set
- Source: Copied from `aircraft.glb` for each ADS-B `Vortex_Type`
- Author: ECAP_Server project asset generation
- License: CC0-1.0
- Modified: Copied and renamed on 2026-07-27
- Notes: These files are placeholders with stable per-type names. Replace individual files through the Cesium model settings page when a type-specific model is available.

## track-point.glb

- Name: ECAP low-poly track point marker
- Source: Generated locally for this project from simple geometric primitives
- Author: ECAP_Server project asset generation
- License: CC0-1.0
- Modified: No
- Notes: The model uses no external texture URL and is used for the selected trajectory point or special business trajectory points.

## base-station.glb

- Name: ECAP low-poly base station mast
- Source: Generated locally for this project from simple geometric primitives
- Author: ECAP_Server project asset generation
- License: CC0-1.0
- Modified: No
- Notes: The model uses no external texture URL. It includes a base plate, vertical mast and antenna panels, with +Z as up for Cesium placement.
