# Entrance Tunnel Mouth (Velodrome and Track Cycling)

The mouth of the players tunnel onto the track apron: a 6 m concrete headwall with a 3.4 by 2.9 m dark opening, a capping band, a yellow lintel stripe and blue reveals. The opening is a recess, not a corridor.

## About

The mouth of the players tunnel onto the track apron: a 6 m concrete headwall with a 3.4 by 2.9 m dark opening, a capping band, a yellow lintel stripe and blue reveals. The opening is a recess, not a corridor. Overall 6.400 x 4.100 x 1.710 m (X x Y x Z), metre units, +Y up, +Z forward, resting on y=0. 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. Static geometry; no rig, animation, collision or navigation data.

## Use with three.js

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

const loader = new GLTFLoader()
loader.load('https://cdn.3dassets.dev/assets/38008/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

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

export function EntranceTunnelMouthVelodromeAndTrackCycling(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/38008/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/38008/v1/model.glb')
```

## <model-viewer>

```html
<model-viewer src="https://cdn.3dassets.dev/assets/38008/v1/model.glb" alt="Entrance Tunnel Mouth (Velodrome and Track Cycling)" camera-controls auto-rotate></model-viewer>
```

## 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/38008/v1/model.glb
# Metres and +Y up are converted to Blender's Z-up scene automatically.
```

## 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)
```

## 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/38008/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
