# transforms

The array of transforms that was used to create a compound shape.

## Declaration

```swift
var transforms: [NSValue]? { get }
```

## Discussion

Discussion You provide this array of NSValue objects, each containing an SCNMatrix4 value, in the init(shapes:transforms:) method to create a compound shape. Use this array along with the sourceObject property to recover the information that was used to create the shape. If the shape was created with the init(geometry:options:) or init(node:options:) method, this property’s value is nil.
