rotation3DEffect(_:axis:anchor:)

Rotates the view’s content by an angle about an axis that you specify as a tuple of elements.

Declaration

nonisolated func rotation3DEffect(_ angle: Angle, axis: (x: CGFloat, y: CGFloat, z: CGFloat), anchor: UnitPoint3D = .center) -> some View

Parameters

angle:
The angle by which to rotate the view’s content.
axis:
The axis of rotation, specified as a tuple with named elements for each of the three spatial dimensions.
anchor:
The unit point within the view about which to perform the rotation. The default value is Center.

Return Value

A view with rotated content.

Discussion

This modifier rotates the view’s content without changing the view’s frame. The following code displays a 3D model with a rotation of 45° about the y-axis using the default anchor point at the center of the view:

Model3D(named: "robot")
    .rotation3DEffect(.degrees(45), axis: (x: 0, y: 1, z: 0))

let rotation = Rotation3D(
    .init(degrees: 45), axis: RotationAxis3D(x: 0, y: 1, z: 0))
Model3D(named: "robot")
    .rotation3DEffect(rotation)
