Rendering Peer Offloading for Distributed VR Scene Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Not all devices have sufficient processing capability to adequately render augmented and virtual reality environments, leading to suboptimal user experiences due to differences in processing power and resolution, and reliance on cloud servers may not always be feasible.
Innovation Solution
A method where a server establishes communication links between client devices to determine which has higher processing capability, designating it as a rendering peer to offload scene rendering tasks, allowing the less capable device to benefit from the more capable device's processing power, thereby enhancing rendering quality and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If cloud servers are used for rendering, then rendering quality is improved, but system complexity and dependency increase
Solution Approach 1:
The patent introduces a rendering peer as an intermediary between the client device and cloud servers. The rendering peer receives rendering requests from less capable devices and provides rendered content, acting as a local mediator that reduces direct dependency on cloud servers while maintaining rendering quality.
Solution Approach 2:
The patent creates a local copy of rendering capability by designating a peer device with sufficient processing power to perform rendering tasks locally. This copying of cloud-based rendering functionality to a local peer device reduces system complexity and eliminates the need for constant cloud server dependency.
2Ease of operation
If devices with lower processing capability attempt to render scenes independently, then device autonomy is maintained, but rendering quality deteriorates
Solution Approach 1:
The patent merges the rendering capabilities of multiple devices by designating a rendering peer that combines its own rendering capacity with the rendering needs of peer devices. This merging allows lower capability devices to maintain autonomy while achieving high rendering quality through collaboration.
Solution Approach 2:
The rendering peer device performs multiple functions: it renders scenes for its own display and simultaneously renders scenes for peer devices with lower processing capability. This multi-functionality allows a single device to serve multiple purposes and maintain device autonomy while improving rendering quality for the network.
3Manufacturing precision
If cloud servers handle all rendering tasks, then rendering quality is improved, but communication overhead and latency increase
Solution Approach 1:
The patent extracts rendering tasks from the cloud server architecture and relocates them to a local rendering peer device. This extraction eliminates the need for constant communication with remote servers, reducing communication overhead and latency while maintaining rendering quality through local processing.
Solution Approach 2:
The rendering peer device performs rendering actions locally and in advance, storing rendered content that can be quickly transmitted to peer devices. This preliminary local rendering action eliminates the need for real-time cloud server communication, reducing latency and communication overhead.
Data Source
AI summary
A device, system and method for distributed processing using a rendering peer is provided. A server establishes first and second communication links with two client devices, and generates scene rendering data for a multi-user virtual platform, the devices to process respective scene rendering data of the platform. The server determines that a second device has higher processing capability than a first device, selects the second device as a rendering peer for the first device, and establishes communication therebetween. The server transmits, via the second communication link, to the second device: command to control the second device to: generate, as the rendering peer, a first rendered scene from first scene rendering data, and transmit the first rendered scene to the first device; and generate a second rendered scene from second scene rendering data, the second rendered scene for providing at the second device.
