Instance Property

transform

The transform applied to the node relative to its parent. Animatable.

Declaration

var transform: SCNMatrix4 { get set }

Discussion

The transformation is the combination of the node’s rotation, position, and scale properties. The default transformation is SCNMatrix4Identity.

When you set the value of this property, the node’s rotation, orientation, eulerAngles, position, and scale properties automatically change to match the new transform, and vice versa. SceneKit can perform this conversion only if the transform you provide is a combination of rotation, translation, and scale operations. If you set the value of this property to a skew transformation or to a nonaffine transformation, the values of these properties become undefined. Setting a new value for any of these properties causes SceneKit to compute a new transformation, discarding any skew or nonaffine operations in the original transformation.

You can animate changes to this property’s value. See Animating SceneKit Content.
