An option for selecting whether to create a group of independent shapes or combine them into a single shape.

## Declaration

```swift
static let keepAsCompound: SCNPhysicsShape.Option
```

## Discussion

Discussion The value for this key is an NSNumber object containing a Boolean value. The default value is true, specifying that SceneKit convert separate geometries into separate shapes and join the resulting shapes. If false, SceneKit creates a single shape approximating the combined form of the geometries.
