# Mast crane (Marina and Yacht Club)

Quayside mast stepping crane 8.4 m tall: a navy slewing column on a bolted base with a lattice jib, a head sheave with a hook block and strop, a hand winch drum and a working platform with a rail. The whole column slews on its base.

## About

Quayside mast stepping crane 8.4 m tall: a navy slewing column on a bolted base with a lattice jib, a head sheave with a hook block and strop, a hand winch drum and a working platform with a rail. The whole column slews on its base. Overall 1.78 by 7.02 by 3.95 m (X by Y by Z). Metre units, +Y up, the working face toward +Z, resting on y=0. The origin is the centre of the base plate on the quay surface, the jib reaching toward +Z at rest. The hoist wire and the strop are modelled solid: wire is flexible and needs a joint per element, so the hook hangs in one pose and only the column slews. Rigid node-transform clips: spin. No skinning. No collision or navigation data. Original CC0 geometry: no marina, club, boat builder, engine maker, sailmaker or regatta is named or depicted, every hull name board, sail number, burgee, flag, sign and plate is blank or an abstract shape, and no real vessel is reproduced.

## 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/38313/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 MastCraneMarinaAndYachtClub(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/38313/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/38313/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/38313/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/38313/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
