# add(_:at:)

Adds an object to the tree corresponding to the specified point in 3D space.

## Declaration

```swift
func add(_ element: ElementType, at point: vector_float3) -> GKOctreeNode
```

## Parameters

- `element`: The object to add to the tree.
- `point`: The point in 2D space to which the object corresponds.

## Return Value

Return Value The tree node containing the newly added object.

## Discussion

Discussion The GKOctree class automatically creates nodes to manage the objects you add to the tree. If you expect to remove an element you’ve added, keep a reference to the node this method returns so you can use the remove(_:using:) method to remove that object quickly.
