What's RealityKit in Apple and how it's changing the AR experience?

RealityKit is Apple's rendering, animation, physics, and audio engine built from the ground up for augmented reality which provides the traditional 3D renderer to make it easy for developers to prototype and produce high-quality AR experiences using RealityKit in your app. RealityKit offers features like video textures, scene understanding using the LiDAR scanner on iPad Pro, Location Anchors, face tracking, and improved debugging tools.

What are the key features of RealityKit?

Scalable performance 

RealityKit uses the GPU to get the most rendering performance available on devices; it also takes advantage of the CPU caches and multi-core processing capabilities to make the simulations smooth for users.

Shared AR experiences

With RealityKit, networking tasks like maintaining a consistent state, optimizing network traffic, handling packet loss, and performing ownership transfers are all handled automatically by the kit without the developer needing to write this semi-boilerplate code themselves.
