# vertices(in:center:orientation:)

Returns the indices of the vertices that lie inside the given volume shape.

## Declaration

```swift
final func vertices(in shape: ClothVolumeShape, center: SIMD3<Float> = SIMD3<Float>(repeating: 0), orientation: simd_quatf = simd_quatf(ix: 0, iy: 0, iz: 0, r: 1)) -> [UInt32]
```

## Parameters

- `shape`: The volume shape to test vertices against.
- `center`: The center position of the shape.
- `orientation`: The orientation of the shape.

## Return Value

Return Value The indices of the vertices that lie inside the shape.
