# init(position0:position1:position2:)

Creates a plane from three positions.

## Declaration

```swift
init(position0 p0: SIMD3<Float>, position1 p1: SIMD3<Float>, position2 p2: SIMD3<Float>)
```

## Discussion

Discussion The plane’s outward normal is computed as cross(p1 − p0, p2 − p1), so the three positions wind counterclockwise when viewed from the outward (culled) side of the plane.
