# init(scale:rotation:translation:)

Creates a projective transform from the specified scale, rotate, and translate transforms.

## Declaration

```swift
init(scale: Size3D = Size3D(width: 1.0, height: 1, depth: 1), rotation: Rotation3D = .zero, translation: Vector3D = .zero)
```

## Parameters

- `scale`: A size structure that specifies the scale.
- `rotation`: A rotation structure that specifies the rotation.
- `translation`: A vector that specifies the translation.
