RealityKit Support

[Ian Wojtowicz]

RealityKit does not use SceneKit (while ARKit does). It would be great to add support for RealityKit in Euclid now that ModelEntities can be dynamically modified.

See 21:40 in https://developer.apple.com/videos/play/wwdc2021/10075/

Yes, I was thinking the same thing. I'll look into it.

Very poorly documented, but an important new feature of RealityKit. Not sure why Apple isn't making this a higher priority topic. (Also automated testing of Apple AR apps is almost impossible.)

I just thought I'd bump this in case it's still in the running for your attention.

[Nick Lockwood]

@iwoj I'd still like to add this, but because it's not something I need myself it's pretty low down the priority list at the moment. If you'd be interested in attempting it yourself, even if it's just a prototype, I'd be happy to accept a PR and take over maintenance of it.

@iwoj hey! I've pushed experimental RealityKit support to the develop branch. It's a WIP but I don't anticipate that the API will change significantly before release.

Please try it out and let me know if you find any problems.
