# geometryIndex

The index of the geometry element whose surface the search ray intersects.

## Declaration

```swift
var geometryIndex: Int { get }
```

## Discussion

Discussion Every SCNGeometry object contains one or more SCNGeometryElement objects that define how its vertices connect to form a surface. This property provides the index of the geometry element intersecting the search ray. For more information about that geometry element, use the geometry’s element(at:) method.
