Cloud VR uses a cloud service provider's infrastructure to render virtual reality (VR) code on a remote server. This rendered code is then streamed to the user's VR headset. This means the heavy processing power needed for VR experiences isn't required by the user's local device, only a sufficient internet connection.
How Cloud VR Works
The process generally involves:
- Remote Rendering: The VR application runs on powerful servers in a data center.
- Streaming: The rendered images and other data are compressed and streamed to the user's headset.
- Low Latency: A high-speed internet connection is crucial for minimizing latency, ensuring smooth and responsive VR experiences.
Advantages of Cloud VR
- Accessibility: Users with less powerful computers or gaming PCs can experience high-fidelity VR.
- Cost-Effectiveness: Reduces the need for expensive high-end VR hardware.
- Scalability: Cloud providers can easily scale resources to accommodate increased demand.
- Enhanced Portability: Users can enjoy VR experiences on various devices without needing top-of-the-line hardware.
Examples of Cloud VR Applications
- Gaming: Playing demanding VR games without needing a powerful gaming PC. Services like PlutoSphere and Shadow are examples, though Shadow's VR support is still in beta (as per Road to VR).
- Professional Use: Cloud VR enables access to powerful VR simulations and applications for professionals in fields like architecture, engineering, and healthcare, as mentioned in the Techviz blog post.
- Remote Collaboration: Enables collaborative VR experiences between users in different locations.
Considerations
While cloud VR offers many advantages, users should be aware of the need for a strong and stable internet connection with low latency for optimal performance.
