A minimal iOS AR app that displays a wave animation using RealityKit2 Geometry Modifier.
- Xcode 13.3
- Target: iOS / iPadOS 15.0+
- SwiftUI, ARKit, RealityKit 2, Metal
In iOS 15.0+, you can use RealityKit 2 Geometry Modifier to modify vertices of 3d models with Metal code. This project shows a sample code that displays a wave animation using a Geometry Modifier. After some seconds, the image texture of the 3d model will be changed. This is also RealityKit 2's feature. Please check the code.
The project includes a USDZ file that has sphere object and plane object. I made it with Blender. The plane is for the surface and has a lot of vertices. With the Geometry Modifier of RealityKit 2, you can move the vertices and make a wave animation. Please check the Metal code and modify as you like.
This is a minimal implementation. Please modify anything you want, and create your own apps.
