## About

A 4 m open ditch: the same birch fence with a boarded trench 1.8 m deep on the take off side and a white guard rail in front of it. Dimensions 4.16 by 2.20 by 3.69 m (X by Y by Z). Metre units, +Y up, +Z front, origin on the footprint at ground level. The trench is modelled as a lined box whose boarded floor is the model base, so the fence itself stands 0.35 m above the origin: sink the model 0.35 m into the surrounding surface and the turf line lands at the top of the boards. Three panels span a 12 m track. Turf course palette: mown and unmown green, rail white, timber, birch brown, steel, charcoal, course green, red, yellow, hardcore grey and glass. No name, number, price or maker mark appears anywhere on this model, and it carries no creature. Static geometry; no rig, animation, collision or navigation data. Functional variant of steeplechase-fence, with its difference modelled rather than animated.

## Use with three.js

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

const loader = new GLTFLoader()
loader.load('https://cdn.3dassets.dev/assets/38598/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

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

export function OpenDitchRacecourseAndParadeRing(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/38598/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/38598/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/38598/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/38598/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
