Animating Augmented Reality Content in .NET MAUI on iOS

Building on interacting with AR content, David Britch shows how to animate a node while still letting users manipulate it. He overlays an image-wrapped sphere representing Earth and rotates it continuously on the Y-axis.

What you’ll learn

• Building a sphere node — creating an SCNSphere and mapping a 2D world map image onto it as a material
• Animating with SCNAction — using RotateBy and RepeatActionForever to spin the node, and a reusable extension method for any SCNNode
• Starting and stopping — toggling the animation with a tap gesture and keyed RunAction/RemoveAction calls
• Keeping it interactive — supporting pinch-to-scale and rotate gestures alongside the animation
