Class

SCNView

A view for displaying 3D SceneKit content.

Overview

In macOS, SCNView is a subclass of NSView. In iOS and tvOS, SCNView is a subclass of UIView. As part of either operating system’s view hierarchy, an SCNView object provides a place for SceneKit content in your app’s user interface. You can create a SceneKit view by using its init(frame:options:) method or by adding it to a nib file or storyboard. To provide content for a SceneKit view, assign an SCNScene object to its scene property.

For additional important methods and properties for working with SceneKit views, see the SCNSceneRenderer protocol. (You can also render SceneKit content into an arbitrary Metal command queue or OpenGL context using the SCNRenderer class, or into a Core Animation layer on macOS using the SCNLayer class. The SCNSceneRenderer protocol defines functionality common to all three SceneKit rendering classes.)

Nested Types

Symbols

Initializing a SceneKit View

init(frame: CGRect, options: [String : Any]? = nil)

Initializes and returns a newly allocated SceneKit view object with the specified frame rectangle and options.

Specifying a Scene

var scene: SCNScene?

The scene to be displayed in the view.

Configuring a View

var backgroundColor: NSColor

The background color of the view.

var allowsCameraControl: Bool

A Boolean value that determines whether the user can manipulate the current point of view that is used to render the scene.

var antialiasingMode: SCNAntialiasingMode

The antialiasing mode used for rendering the view’s scene.

var preferredFramesPerSecond: Int

The animation frame rate that the view uses to render its scene.

Playing Action and Animation in a View’s Scene

func pause(Any?)

Pauses playback of the view’s scene.

func play(Any?)

Resumes playback of the view’s scene.

func stop(Any?)

Stops playback of the view’s scene and resets the scene time to its start time.

Capturing a View Snapshot

func snapshot()

Renders the view’s scene into a new image object.

Working with a View’s OpenGL ES Context

var eaglContext: EAGLContext?

The OpenGL ES context that the view uses to render its contents.

Working with a View’s OpenGL Context

var openGLContext: NSOpenGLContext?

The OpenGL context that the view uses to render its contents.

var pixelFormat: NSOpenGLPixelFormat?

The view’s OpenGL pixel format.

Constants

View Initialization Options

Dictionary keys specifying initialization options, used in the SCNView initializer.

SCNAntialiasingMode

Modes for antialiased rendering of the view’s scene, used by the SCNView property.
