# Spinning gem, red (Pickups and Collectibles)

Eight-sided brilliant-cut red gem, 0.31 m across the girdle, held in a gold collet of eight claws. Flat shaded so every facet catches the light separately.

## About

A brilliant cut spun on eight segments: pointed culet, pavilion, a girdle 0.023 m deep, a sloped crown and a flat table. Eight gold claws grip the girdle between the facets. The whole cut is flat shaded, so the eight pavilion facets and eight crown facets each take their own normal. Bounding size 0.31 by 0.26 by 0.31 m; metres, +Y up, +Z forward. Origin: free, at the centre of the stone, on its spin axis, because a collectible like this is hung in mid-air at whatever hover height the level needs and a base origin would put it on the floor. The geometry surrounds the origin, reaching 0.129 m below it and 0.129 m above it. Clips: `bob` (2.2 s), `spin` (1.8 s). Rigid node animation only: named nodes with translation, rotation and scale clips, no skinned rig and no skeleton. No collision volumes and no navigation data. Opaque materials throughout; the pack uses no alpha blending and no transmission.

## 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/11203/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 SpinningGemRedPickupsAndCollectibles(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/11203/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/11203/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/11203/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/11203/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
