Splash Portals
I think splash screens have the potential to feel really magical on this platform. Incorporating 3D elements into app launches or onboarding flows could be a new method for onboarding and maintaining engagement for apps moving forward. These are some prototypes I made with the Portal Component inside RealityKit leveraging particle emitters and text views to welcome a visitor on app launch.
I also think portal to mixed space transitions have a lot of potential to feel magical here; this is what I plan to expand upon with this prototype moving forward. I would try to create this idea by placing an occlusion material plane behind the portal, and sync up the particle emitter so that when particles appear to reach the clipping plane of the portal, the particles behind the occlusion material plane begin emitting through the portal mesh.
