# pointOfView

The node from which the scene’s contents are viewed for rendering.

```
var pointOfView: SCNNode? { get set }
```

## Discussion

Use a node with an [`SCNCamera`](/documentation/SceneKit/SCNCamera) instance assigned to its [`camera`](/documentation/SceneKit/SCNNode/camera) property to view a scene. The node provides the position and direction of a virtual camera, and the camera object provides rendering parameters such as field of view and focus.

For debugging lights and shadows, you can also designate a spotlight (an [`SCNLight`](/documentation/SceneKit/SCNLight) object whose [`type`](/documentation/SceneKit/SCNLight/type) property is [`spot`](/documentation/SceneKit/SCNLight/LightType/spot)) as a point of view. In this case, the light’s [`spotInnerAngle`](/documentation/SceneKit/SCNLight/spotInnerAngle) property determines the field of view, and its [`zNear`](/documentation/SceneKit/SCNLight/zNear) and [`zFar`](/documentation/SceneKit/SCNLight/zFar) properties determine the near and far extents of the region that is visible onscreen (also known as the *viewing frustum*).

In either case, the direction of view is along the negative z-axis of the node’s local coordinate space.
