# Warm Up Roller Set (Velodrome and Track Cycling)

A three drum roller set for warming up on: a low charcoal frame, two rear drums and one front drum on steel rails, with the belt between them modelled as a solid strip. Each drum is a named node on its own axle and spins. 1.5 m long.

## About

A three drum roller set for warming up on: a low charcoal frame, two rear drums and one front drum on steel rails, with the belt between them modelled as a solid strip. Each drum is a named node on its own axle and spins. 1.5 m long. Overall 0.620 x 0.395 x 1.500 m (X x Y x Z), metre units, +Y up, +Z forward, resting on y=0. Named nodes on their own pivots: drum-rear-a, drum-rear-b, drum-front. Velodrome and Track Cycling / velodrome-lp-v1: faceted pale pine track boards, grey concrete, brushed steel, charcoal rubber and three painted accents in blue, red and yellow, with embedded procedural wood and concrete maps and no custom shaders. There are no people in this pack, and every screen, board, banner and panel face is blank: nothing here names or depicts a real venue, team, race or manufacturer. Rigid node-transform clips: spin. 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/38015/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 WarmUpRollerSetVelodromeAndTrackCycling(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/38015/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/38015/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/38015/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/38015/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
