## About

A towable ground power unit: a yellow cabinet on four wheels with louvred vents, a lit control panel, an output cable coiled on its hook and a tow handle. Every wheel rolls on its own node. Dimensions 1.48 x 1.34 x 2.38 m (X x Y x Z). Origin at the footprint centre, resting on y = 0; metres, +Y up, nose toward +Z, wing span and wheel axles along X. Named pivots: wheel-rf at (0.36, 0.2, 0.26); wheel-lf at (-0.68, 0.2, 0.26); wheel-lb at (-0.68, 0.2, -0.94); wheel-rb at (0.36, 0.2, -0.94). Rigid node-transform clips wheel-roll drive named nodes on their own pivots. No skinning and no skeleton, so the retraction linkage, rotor flapping and lead-lag, propeller pitch change, the swashplate and wing flex are all deliberately static. Sixteen material palette of airframe white, deep blue, warm red, airfield yellow, bare aluminium, steel grey, charcoal, near black tarmac, light grey concrete, olive and tinted glazing, plus five emissive lighting materials for navigation, strobe, taxiway, threshold and interior lights. Flat colours, no texture maps. Original generic design with no manufacturer, type designation, livery, registration or operator marking. Free 3D model for Unity, Godot, Unreal, three.js and Blender. No collision or navigation data.

## Use with three.js

```js
import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'
import { AnimationMixer } from 'three'

let mixer

const loader = new GLTFLoader()
loader.load('https://cdn.3dassets.dev/assets/32839/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
  mixer = new AnimationMixer(gltf.scene)
  mixer.clipAction(gltf.animations[0]).play()
})

// Call from your render loop; deltaSeconds is time since the previous frame.
function updateAssetAnimation(deltaSeconds) {
  mixer?.update(deltaSeconds)
}
```

## React Three Fiber

```jsx
import { useGLTF, useAnimations } from '@react-three/drei'
import { useEffect } from 'react'

export function GroundPowerUnitCartAircraftFleetAndAirfield(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/32839/v1/model.glb')
  const { actions, names } = useAnimations(animations, scene)
  useEffect(() => {
    const action = actions[names[0]]
    action?.reset().play()
    return () => { action?.stop() }
  }, [actions, names])
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/32839/v1/model.glb')
```

## Blender

```python
# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.
import bpy
bpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/32839/v1/model.glb
# Metres and +Y up are converted to Blender's Z-up scene automatically.
# Clips arrive as actions; play them from the Dope Sheet > Action Editor.
```

## Godot

```gdscript
# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.
var packed := load("res://models/model.glb") as PackedScene
var model := packed.instantiate()
add_child(model)
var player := model.find_child("AnimationPlayer", true, false) as AnimationPlayer
player.play(player.get_animation_list()[0])
```

## Unity

```csharp
// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,
// or load it at runtime straight from the CDN:
using GLTFast;
var gltf = new GltfImport();
if (await gltf.Load("https://cdn.3dassets.dev/assets/32839/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
