Static Rendering for Videoconference Virtual Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional videoconferencing technologies lack the social interaction and immersive experience of in-person meetings, and face performance issues with large participant numbers due to bandwidth and hardware limitations, leading to slow performance and reduced realism in virtual environments.
Innovation Solution
A computer-implemented method for efficient rendering of a three-dimensional virtual environment, where a virtual camera determines movement to render fixed and dynamic objects separately, creating a combined image by stitching static and dynamic elements, and optimizing graphics quality based on device capabilities, allowing for improved social interaction and realistic rendering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video streams from multiple participants are transmitted in real-time, then social interaction and communication capability are improved, but network bandwidth consumption and device performance requirements increase
Solution Approach 1:
The patent segments the rendering process by separating static background elements from dynamic participant elements. The background environment is pre-rendered and reused across frames, while only dynamic elements (participants, avatars, camera movements) are re-rendered. This segmentation significantly reduces the computational load and bandwidth requirements for transmitting video streams while maintaining social interaction capabilities.
Solution Approach 2:
The patent applies preliminary action by pre-rendering static background environments and preparing them for reuse. Instead of rendering the entire scene from scratch for each frame, the system prepares background assets in advance and only updates dynamic portions, reducing real-time processing requirements and enabling smoother multi-participant interactions.
2Adaptability or versatility
If high-quality graphics rendering is performed for realistic virtual environments, then immersion and social experience are improved, but computing power requirements and device performance increase
Solution Approach 1:
The rendering system is segmented into static background components and dynamic participant components. Static backgrounds are rendered once or infrequently, while dynamic elements are updated only when necessary. This segmentation allows high-quality graphics for immersive experiences without requiring continuous high computing power consumption.
Solution Approach 2:
The patent applies local quality by rendering different parts of the virtual environment at different quality levels and update frequencies. Static backgrounds maintain high visual quality for immersion but are updated less frequently, while dynamic participant elements receive updates based on their movement and importance. This localized quality approach balances immersive experience with computing power constraints.
3Manufacturing precision
If the entire virtual environment is re-rendered for every frame update, then rendering accuracy and visual quality are maintained, but rendering time and system performance decrease
Solution Approach 1:
The patent divides the rendering process into static background rendering and dynamic element rendering. By segmenting the scene graph into immutable background objects and mutable participant objects, the system can update only the necessary portions for each frame, maintaining rendering accuracy while significantly improving rendering speed and system performance.
4Adaptability or versatility
If videoconferencing systems support large numbers of participants, then collaboration capability and group interaction are improved, but network bandwidth and device performance deteriorate
Solution Approach 1:
The system segments participant rendering into individual update cycles rather than rendering all participants simultaneously. Each participant's avatar and video feed are updated independently based on their movement and activity, allowing the system to support large numbers of participants while maintaining performance stability through distributed, incremental updates.
