# setIdentity()

Sets all factors of the transform to those of the identity transformation.

## Declaration

```swift
func setIdentity()
```

## Discussion

Discussion The identity transform is equivalent to the lack of a transformation, so an object affected by the transform uses the same coordinate space as its parent. Calling this method also erases any time-sampled data, creating a static transform.
