## About

Original optical star projector with two smooth spherical optical heads, thirty genuinely recessed lens barrels, supported yoke, central spindle, drive hubs and heavy pedestal interface. No projected stars or optical simulation. Dimensions 0.83 × 2.10 × 0.81 m (X × Y × Z). Metre units, +Y up, +Z front; origin on the ground at the footprint centre unless stated. Original midnight-blue and ivory public optical astronomy centre. Static optics without projection, tracking, imaging or scientific calibration claims. 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/31825/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

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

export function StarProjectorPlanetariumAndOpticalObservatory(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/31825/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/31825/v1/model.glb')
```

## <model-viewer>

```html
<model-viewer src="https://cdn.3dassets.dev/assets/31825/v1/model.glb" alt="Star Projector (Planetarium and Optical Observatory)" 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/31825/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/31825/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
