# orientationMode

The mode defining whether and how particles may rotate.

## Declaration

```swift
var orientationMode: SCNParticleOrientationMode { get set }
```

## Discussion

Discussion A particle’s angle (or orientation) is independent from its direction of motion. For example, a smoke effect may use a small image of a cloud for each particle, which stays at the same angle as the smoke rises, but a snow effect may use an image that flips and rotates as each snowflake falls. For possible orientation modes, see SCNParticleOrientationMode. The default value is SCNParticleOrientationMode.billboardScreenAligned.
