Qual è la differenza tra una piattaforma VR e un motore VR?

Un motore VR (di solito un Game Engine che supporta la VR) vive sopra una piattaforma VR. I motori di gioco possono supportare più piattaforme VR.

La piattaforma VR fornisce:

1. Un kit di sviluppo software che dà al motore di gioco l'accesso ai sensori dell'auricolare.
2. Un livello di compositing che fornisce funzioni come "Chaperone" o "Guardian" che aiutano le persone a non incorrere nei loro mobili, e funzioni come "Asynchronous Space Warp" che aiutano le esperienze VR a mantenere un frame rate regolare.
3. A store where users can purchase VR experiences without leaving VR.
4. A matchmaking service where users can find people to play games with or join social experiences without leaving VR.

A Game Engine provides:

1. An easy way for developers to support VR hardware without having to learn how the underlying platform SDK works, and without needing deep knowledge of the specifics of the graphics APIs that are used by various Operating Systems and devices.
2. Streamlined design patterns for developing 3D content that helps keep projects organized.
3. An easy way for developers to support multiple VR platforms with a single code base.
4. Unity and Unreal now have features that allow developers to build VR experiences while actually wearing the headset and experiencing the environments in VR.

Examples of Game Engines:

1. Unity 3D
2. Unreal Engine 4
3. CryEngine
4. Frostbite

Examples of VR Platforms:

1. SteamVR
2. Oculus SDK/Oculus Home/Samsung Gear VR Powered by Oculus
3. Windows Holographic
4. Google VR (Daydream)
5. PlayStation VR
