3D Scene Rendering Resolution via Dual-Layer Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image rendering techniques in extended reality technologies result in a loss of definition due to double sampling, which reduces the resolution of rendered maps when projecting a scene layer onto a display screen.
Innovation Solution
An image rendering method and apparatus that determines specific pixel attributes and renders a target map onto a render layer, allowing for increased resolution of highlighted regions in the 3D on-screen scene without affecting the rendering efficiency, using modules for pixel determination, target map rendering, and target rendering image determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a to-be-rendered map is rendered onto the scene layer first and then displayed on the screen, then the rendering performance is improved, but the definition of the rendered map is reduced due to double sampling
Solution Approach 1:
The patent segments the rendering process into two independent stages: (1) rendering the to-be-rendered map onto an independent render layer at high resolution, and (2) compositing the render layer with the scene layer. This segmentation eliminates the double sampling issue by avoiding intermediate rendering on the scene layer, thus resolving the contradiction between rendering performance and map definition.
Solution Approach 2:
The patent introduces an independent render layer as an intermediary between the to-be-rendered map and the final display. This render layer serves as a buffer that preserves high-resolution map data without requiring immediate composition with the scene layer, thereby maintaining definition while enabling efficient rendering through deferred compositing.
2Productivity
If the resolution of the scene layer is reduced to improve rendering performance, then the rendering speed is increased, but the display quality is degraded
Solution Approach 1:
The patent moves the high-resolution rendering operation from the traditional scene layer dimension to a separate render layer dimension. This allows the scene layer to use lower resolution for performance while the render layer maintains high resolution for quality, effectively resolving the contradiction by operating in an additional dimensional space.
Solution Approach 2:
The patent applies local quality by allowing different layers to have different resolution characteristics. The render layer maintains high resolution specifically for the map content that requires definition, while the scene layer can use lower resolution for other elements, thus achieving both speed and quality where needed.

AI summary
An image rendering method includes the following: A to-be-processed pixel in a 3D scene layer, a target pixel in the 3D scene layer, a pixel attribute of the to-be-processed pixel, and a pixel attribute of the target pixel are determined according to a map attribute of a to-be-processed map of a 3D on-screen scene, and a map attribute of a target map of the 3D on-screen scene; the target map is rendered onto a render layer according to the map attribute of the target map; a target rendering image corresponding to the 3D on-screen scene is determined based on the 3D scene layer and the render layer, and the target rendering image is projected and displayed.
