Virtual Environment Frame Controller for Lag Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual environment systems face challenges in maintaining a consistent frame rate, leading to lag and loss of synchronization, especially when dealing with complex scenes and varying user interactions, which negatively impacts the user experience.
Innovation Solution
The method involves dynamically adjusting the number and priority of objects in the virtual environment output based on client capabilities, using a frame controller module to modify the frame rate and object rendering, prioritizing critical elements and user-specific preferences, and distributing rendering tasks to optimize performance across multiple clients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the virtual environment renders all objects at full detail to maintain visual quality, then the rendering complexity increases, but the frame rate drops below the target rate causing lag and desynchronization
Solution Approach 1:
The system applies different rendering qualities to different objects based on their priority and relevance to the user. High-priority objects (e.g., avatars, interactive elements) are rendered at full detail, while low-priority objects (e.g., background elements, distant objects) are rendered at reduced quality or omitted entirely. This selective approach maintains visual quality for critical elements while reducing overall rendering complexity to achieve the target frame rate.
2Loss of information
If the virtual environment includes all virtual objects in the output to maintain completeness of the scene, then the data transmission volume increases, but the client device cannot process frames quickly enough causing loss of synchronization
Solution Approach 1:
The system extracts and transmits only the essential objects and data needed for the current frame, excluding non-critical objects that can be inferred or are less important to the user experience. By selectively including only necessary objects in the output data, the transmission volume and processing requirements are reduced, enabling the client to keep up with the frame rate and maintain synchronization with the server.
3Productivity
If the system maintains a high target frame rate for smooth user experience, then the rendering load on client devices increases, but devices with limited capabilities cannot achieve the target rate
Solution Approach 1:
The system dynamically adjusts rendering parameters such as object detail level, texture resolution, and number of rendered objects based on the client device's capabilities and current performance metrics. By changing these parameters adaptively, the system can maintain the target frame rate on high-end devices while providing acceptable performance on less capable devices, ensuring broad compatibility without compromising the user experience on powerful systems.
Data Source
AI summary
A virtual environment in generated in a server where at least one object representative of an entity interacts with other objects or attributes of the environment. A desired frame rate for rendering the virtual environment is identified, and compared to a maximum achievable frame rate at a client device. If the maximum achievable frame rate is slower than the desired frame rate, the number of objects displayed within the virtual environment is modified, in accordance with one or more rule sets, until the maximum achievable frame rate is at or near the desired frame rate. In addition, a server may provide and synchronize output for clients participating in the virtual environment using different target frame rates.
