Image Rendering via Interleaved Buffer Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a trade-off between rendering quality and speed in image rendering, where high-quality rendering, such as photo-realistic images, requires significant computing power and time, often necessitating the rendering of image tiles, which limits interactivity and user experience.
Innovation Solution
The method involves splitting an image into smaller interleaved buffers, allowing for progressive rendering and blending of lower-resolution views with higher-quality details, enabling faster initial display and dynamic quality adjustments without increasing pixel count, using techniques like ray tracing and camera angle adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-quality rendering (e.g., photo-realistic images) is used, then rendering quality is improved, but rendering time and computing power requirements increase significantly
Solution Approach 1:
The patent divides the image into multiple tiles and further segments each tile into multiple interleaved buffers (e.g., four buffers per tile). This segmentation allows the rendering system to process and display portions of the image concurrently at different quality levels, resolving the contradiction between rendering quality and time by enabling progressive quality improvement without waiting for complete high-quality rendering of the entire image.
Solution Approach 2:
The patent implements dynamic rendering quality adjustment where different portions of the image can be rendered at different quality levels simultaneously. The system dynamically switches between low-quality fast rendering and high-quality detailed rendering based on the specific tile and buffer being processed, allowing the image to progressively improve in quality while maintaining interactivity.
2Productivity
If conventional tile-based rendering is used, then rendering speed is improved, but interactivity and user experience deteriorate due to requiring users to wait for portions to render
Solution Approach 1:
The patent applies preliminary action by pre-splitting the image into tiles and interleaved buffers before rendering begins. This preparation allows the system to start displaying low-quality versions of the image immediately while progressively adding high-quality details in the background, eliminating the need for users to wait for rendering to complete before seeing any content.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining a continuous rendering pipeline where low-quality tiles are rendered and displayed first, then progressively replaced by high-quality versions. The interleaved buffer mechanism ensures that rendering operations continue without interruption, always providing the user with the latest available image data at the highest possible quality level.
3Manufacturing precision
If the entire image is rendered at high quality simultaneously, then rendering quality is improved, but device complexity and computing power requirements increase
Solution Approach 1:
The patent segments the image into tiles and further into interleaved buffers, allowing the rendering system to distribute computing workload across multiple smaller units. This segmentation enables high-quality rendering of individual portions without requiring the system to process the entire image at maximum quality simultaneously, thereby reducing peak computing power requirements and system complexity.
Solution Approach 2:
The patent applies local quality by rendering different portions of the image at different quality levels based on their specific requirements. Not all areas of the image need the same level of detail, so the system can allocate computing resources dynamically, applying high-quality rendering only where necessary while using faster, lower-quality rendering for less critical areas.

AI summary
Systems, methods, and computer program products receive an image request identifying an image having a width and a height. A number of interleaved buffers is identified, each of the interleaved buffers operable to store data associated with the image. The image is split into each of the interleaved buffers on a computing device. An interleaved image is displayed corresponding to at least one of the interleaved buffers, where the interleaved image having substantially the same width and height of the image.
