# projectPoint(_:)

Projects a point from the 3D world coordinate system of the scene to the 2D pixel coordinate system of the renderer.

```
func projectPoint(_ point: SCNVector3) -> SCNVector3
```

## Parameters

`point`

A point in the world coordinate system of the renderer’s scene.

## Return Value

The corresponding point in the screen-space (view, layer, or GPU viewport) coordinate system of the scene renderer.

## Discussion

The z-coordinate of the returned point describes the depth of the projected point relative to the near and far clipping planes of the renderer’s viewing frustum (defined by its [`pointOfView`](/documentation/SceneKit/SCNSceneRenderer/pointOfView) node). Projecting a point on the near clipping plane returns a point whose z-coordinate is `0.0`; projecting a point on the far clipping plane returns a point whose z-coordinate is `1.0`.
