## About

Quarter turn of a descending helix on an 8 m radius: 90 degrees of banked left hand curve losing 2 m of height, with the pitch and the bank eased to nothing at both ports. Free 3D model for theme park, roller coaster and tycoon game scenes in Unity, Godot, Unreal, three.js and Blender. Overall 8.53 by 2.50 by 8.53 m (X by Y by Z). Metre units, +Y up, +Z forward. Pivot on the grid origin at the high port. Four of these stack into a full 360 degree helix losing 8 m; because the pitch eases out at each port the piece also joins level track directly. Static geometry; no rig, 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/28628/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

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

export function CoasterHelixQuarterThemeParkRidesAndCoasters(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/28628/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/28628/v1/model.glb')
```

<model-viewer src="https://cdn.3dassets.dev/assets/28628/v1/model.glb" alt="Coaster Helix Quarter (Theme Park Rides and Coasters)" 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/28628/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/28628/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
