# init(influences:influencesPerVertex:)

Associates every vertex in the mesh with a fixed number of influences per vertex.

## Declaration

```swift
init(influences: MeshBuffers.JointInfluences, influencesPerVertex: Int)
```

## Parameters

- `influences`: Buffer of joint influences.
- `influencesPerVertex`: The number of consecutive influences used by each vertex.

## Discussion

Discussion note: The buffer should contain vertexCount * influencesPerVertex elements.
