## About

The aerial appliance with the boom raised to about 54 degrees and the three sections extended over the nose, cage at working height. Dimensions 4.97 by 14.32 by 10.91 m (X by Y by Z). Metre units, +Y up, +Z front, origin on the footprint at ground level. Animated pivot nodes: wheel-fl at (-1.02, 0.50, 2.90) m; wheel-fr at (1.02, 0.50, 2.90) m; wheel-rl at (-1.02, 0.50, -2.30) m; wheel-rr at (1.02, 0.50, -2.30) m; wheel-rl2 at (-1.02, 0.50, -3.60) m; wheel-rr2 at (1.02, 0.50, -3.60) m; cab-door-left at (-1.16, 1.85, 4.03) m; cab-door-right at (1.16, 1.85, 4.03) m. Functional variant for an incident scene: the boom pose is baked into the geometry, so the lift node carries no clip here. Wheels and cab doors still animate. Origin remains on the chassis footprint at ground level. Service palette: signal red, high visibility yellow, charcoal, galvanised steel, station brick and glass, with scorch and soot on the incident pieces. Rigid node-transform clips: open, close and wheel-roll. No skinning. No collision or navigation data. Functional variant of ladder-platform-appliance, with its open pose modelled rather than animated.

## 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/29897/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 LadderPlatformApplianceBoomRaisedFireAndEmergencyServices(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/29897/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/29897/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/29897/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/29897/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
