Real-time 3D VR Video Rendering with Stereoscopic Eye Perspective
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VR video rendering technologies lack realism and immersion due to simple superimposed rendering of 3D video and graphics, failing to simulate the distinct perspectives of the left and right eyes, leading to eye discomfort and dizziness during prolonged viewing.
Innovation Solution
A real-time aliasing rendering method for 3D VR video and virtual three-dimensional scenes, which involves collecting and processing 3D camera signals to generate texture data, creating a virtual 3D scene, adjusting virtual camera parameters, and overlaying texture data to simulate the perspectives of the left and right eyes, ensuring realistic and immersive rendering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple superimposed rendering of 3D video and graphic images is used, then device complexity is reduced, but realism and immersion are deteriorated
Solution Approach 1:
The patent divides the rendering process into separate left-eye and right-eye rendering paths, with independent texture mapping and parameter adjustment for each eye. This segmentation enables realistic stereoscopic effects while maintaining manageable system complexity through modular processing.
Solution Approach 2:
The patent transitions from 2D superimposed rendering to 3D stereoscopic rendering by introducing depth information and separate perspective views for left and right eyes. This dimensional enhancement creates realistic spatial perception without requiring overly complex hardware.
2Ease of operation
If simple superimposed rendering is used, then ease of operation is improved, but immersion is deteriorated
Solution Approach 1:
The rendering system is segmented into independent left-eye and right-eye processing channels, each with its own texture mapping and parameter control. This modular approach maintains operational simplicity while achieving immersive 3D effects through systematic separation of visual pathways.
3Device complexity
If subsequent re-production is used to output to virtual equipment, then device complexity is reduced, but viewing comfort is deteriorated
Solution Approach 1:
The patent implements separate rendering pipelines for left-eye and right-eye views, with independent texture mapping and camera parameter adjustment. This segmentation ensures that each eye receives appropriately adjusted visual information, eliminating the eye discomfort caused by improper stereoscopic presentation while maintaining manageable equipment complexity.
