I would like to develop a desktop app for MacOS that uses computer camera with RealityKit to display 3D cube in front of camera at some distance. I've started a project for MacOS using RealityKit, and immediately noticed that it is not using MacOS camera , not even asking for camera access permission and same project work fine for IOS.
Is the same functionality not available on both MacOS and iOS, or am I just doing something wrong?
RealityKit "runs" on macOS, but it doesn't use the camera for any input - you have to create your own virtual camera and arrange all the positioning yourself. I made a SwiftUI view wrapped (for macOS) that lets me see RealityKit models and representations that you're welcome to dig through and take what you'd like from it: https://github.com/heckj/CameraControlARView - although if you use it as a package, make sure to use the release version, because I've got it somewhat torn apart working on adding some different camera motion modes to the original creation.
