# Met Mast With Instruments (Wind and Solar Energy Farm)

A 21 m triangular lattice met mast: braced legs on three pad feet, instrument booms carrying a wind vane, a radiation shield and a logger cabinet, and a cup anemometer that turns at the top.

## About

A 21 m triangular lattice met mast: braced legs on three pad feet, instrument booms carrying a wind vane, a radiation shield and a logger cabinet, and a cup anemometer that turns at the top. Dimensions 1.63 by 21.28 by 2.75 m (X by Y by Z). Metre units, +Y up, +Z front, origin on the footprint at ground level. Animated pivot nodes: anemometer at (0.00, 21.07, 1.75) m. The anemometer cups are the only moving node, pivoted on the top boom. Guy wires are not modelled and the wind vane is solid and static: a rigid node transform has nothing sensible to do with either. Renewables low-poly palette: turbine white, concrete grey, site grass, galvanised steel, charcoal, photovoltaic blue, safety yellow and warning red. Rigid node-transform clips: spin. No skinning. No collision or navigation data.

## 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/34054/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 MetMastWithInstrumentsWindAndSolarEnergyFarm(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/34054/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/34054/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/34054/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/34054/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
