# boundingBox

The physics shape is the smallest box containing the geometry.

## Declaration

```swift
static let boundingBox: SCNPhysicsShape.ShapeType
```

## Discussion

Discussion This option provides the lowest level of detail and the fastest simulation performance. Use it for generally box-shaped physics bodies or when constructing a compound physics shape.
