## About

Three axle aerial ladder platform appliance with a stowed three section telescopic boom, a work cage, four outrigger jacks and a slew ring. Dimensions 4.97 by 3.40 by 10.57 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; boom-lift at (0.00, 2.05, -2.00) m. Body 9.90 m long. The boom heel is a named lift node and the six wheels and two cab doors are named spin and hinge nodes. The boom slew ring, the outrigger jacks and the boom hydraulic linkage are deliberately static: a rigid node transform cannot carry the boom through a slew and a lift at once, and faking the ram linkage would cost a consumer more than it gives. Invented plain livery, no crest or unit marking. 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: cab-door-open, cab-door-close, door-open, door-close and wheel-roll. No skinning. 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/29898/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 LadderPlatformApplianceFireAndEmergencyServices(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/29898/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/29898/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/29898/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/29898/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
