# init(from:zoom:name:)

Creates a camera that looks toward the preview center from a specified unit point.

## Declaration

```swift
init(from point: UnitPoint3D, zoom: Double = 1, name: String? = nil)
```

## Parameters

- `point`: The point in 3D space where to place the camera, given as a unit point relative to the preview center.
- `zoom`: An optional amount by which to scale the distance from the camera to the preview center. Values larger than 1 move the camera closer to the preview center. Fractional values move the camera away.
- `name`: An optional name that the canvas uses to label the camera.

## Discussion

Discussion Use one or more cameras with one of the preview macros that takes a cameras input — like Preview(_:traits:body:cameras:) — to create custom viewpoints for the preview. The canvas offers custom cameras in its camera picker along with a set of standard cameras.
