# SCNBillboardConstraint

A constraint that orients a node to always point toward the current camera.

## Declaration

```swift
class SCNBillboardConstraint
```

## Overview

Overview An SCNBillboardConstraint object automatically adjusts a node’s orientation so that its local z-axis always points toward the pointOfView node currently being used to render the scene. For example, you can use a billboard constraint to efficiently render parts of a scene using two-dimensional sprite images instead of three-dimensional geometry—by mapping sprites onto planes affected by a billboard constraint, the sprites maintain their orientation with respect to the viewer. To attach constraints to an SCNNode object, use its constraints property.
