Embedded Media Layer Separation for 3D Rendering Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for rendering multi-layer content in a 3D environment suffer from resolution loss, warping, and other defects due to treating high-resolution content as a single texture, which complicates shader rendering and requires depth information to distinguish visible layers.
Innovation Solution
Separate high-resolution and low-resolution content layers for fragment shader rendering, removing background content from low-resolution layers to simplify shader processing and ensure high-resolution content visibility, and use different sampling techniques to avoid intermediate resampling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multi-layer content is rendered as a single texture, then rendering complexity is reduced, but resolution loss and warping occur in high-resolution content
Solution Approach 1:
The patent segments multi-layer content into distinct layers based on resolution characteristics. High-resolution content layers are separated from low-resolution content layers, allowing each layer to be rendered with appropriate sampling techniques. This segmentation prevents resolution loss and warping in high-resolution content while maintaining manageable rendering complexity through layer-specific processing.
2Measurement precision
If depth information is used to distinguish visible layers, then content visibility accuracy is improved, but shader rendering complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-processing multi-layer content to identify and separate high-resolution and low-resolution layers before rendering. This pre-separation allows the rendering system to apply appropriate sampling techniques to each layer without requiring complex real-time depth analysis during shader execution, thus maintaining visibility accuracy while reducing shader complexity.
3Productivity
If high-resolution and low-resolution content are rendered together, then complete scene rendering is achieved, but warping and resolution loss occur
Solution Approach 1:
The patent applies local quality by assigning different rendering qualities and sampling techniques to different content layers based on their resolution characteristics. High-resolution content layers receive higher-quality rendering with appropriate sampling to prevent warping, while low-resolution content layers use standard rendering. This localized quality approach ensures complete scene rendering while maintaining high content quality where needed.

AI summary
Various implementations disclosed herein include devices, systems, and methods that separate multi-layer/multi-resolution content for rendering. For example, a process may obtain obtaining multi-layer content comprising a first layer of content and one or more second layers of content having a resolution differing from a resolution of the first layer of content. The process may further separate the first layer of content of the multi-layer content thereby providing a remaining portion of the multi-layer content for rendering. The process may further render a view of a 3D environment including a depiction of the multi-layer content at a 3D position within the 3D environment. The depiction of the multi-layer content may be rendered by blending the separated first layer of content and the texture of the remaining portion of the multi-layer content.
