Bin Filtering Two-Pass Rendering GPU Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing graphics processing technologies face inefficiencies in rendering images due to the need for expanded-bin modes, which increase processing and memory overhead and reduce GPU efficiency, especially when handling overlapping pixels between bins.
Innovation Solution
A method and system for graphics processing that splits an image into bins and renders a first subset of pixels during a first pass, deferring the rendering of edge and intermediate pixels until a second pass, thereby avoiding the need for expanded-bin modes and reducing resource usage and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expanded-bin mode is used to handle overlapping pixels between bins, then image rendering completeness is improved, but processing overhead and memory usage increase
Solution Approach 1:
The patent segments the image into multiple bins for parallel processing, and further segments the pixels within each bin into three subsets (first, second, and third subsets). This multi-level segmentation allows the system to handle overlapping pixels efficiently by processing different pixel subsets in different rendering passes, avoiding the need for expanded-bin mode while maintaining rendering completeness.
Solution Approach 2:
The patent performs preliminary actions by rendering the first subset of pixels during a first rendering pass before handling the overlapping pixels. The second and third subsets of pixels are deferred to a second rendering pass. This preliminary processing of non-overlapping pixels first allows subsequent processing of overlapping pixels with reduced complexity.
2Manufacturing precision
If expanded-bin mode is used to handle overlapping pixels, then rendering accuracy is improved, but GPU efficiency decreases
Solution Approach 1:
The patent uses periodic action by implementing a two-pass rendering process. The first rendering pass processes the first subset of pixels, and the second rendering pass processes the second and third subsets of pixels. This periodic, multi-pass approach maintains rendering accuracy for overlapping pixels while improving GPU efficiency by avoiding the continuous overhead of expanded-bin mode.
Solution Approach 2:
By completing the rendering of the first subset of pixels in advance during the first pass, the system prepares data that can be reused during the second pass when processing overlapping pixels. This preliminary action reduces redundant computations and improves overall GPU efficiency while maintaining rendering accuracy.
3Adaptability or versatility
If expanded-bin mode is used to support post-rendering effects, then filtering capability is improved, but memory overhead increases
Solution Approach 1:
The patent segments pixels into different subsets based on their spatial relationships and processing requirements. By segmenting overlapping pixels into the second and third subsets that are processed in a dedicated second rendering pass, the system provides filtering capability for post-rendering effects without requiring the expanded memory allocation of expanded-bin mode.
Solution Approach 2:
The patent discards the need for expanded-bin memory structures and recovers memory resources by using standard bin structures with a multi-pass processing approach. The system temporarily stores only the necessary pixel subsets between passes rather than maintaining expanded bin structures throughout, reducing overall memory overhead while preserving filtering capability.
4Speed
If all pixels are rendered in a single pass, then processing speed is improved, but image quality deteriorates due to inability to handle overlapping pixels
Solution Approach 1:
The patent implements periodic action through a two-pass rendering process where the first pass processes the first subset of pixels at high speed, and the second pass processes the second and third subsets. This periodic approach maintains overall processing speed by enabling parallel processing of non-overlapping pixels while ensuring image quality through dedicated handling of overlapping pixels in the second pass.
Solution Approach 2:
The first rendering pass performs preliminary processing of the first subset of pixels, establishing a foundation that enables efficient processing of overlapping pixels in the second pass. This preliminary action allows the system to maintain high processing speed by avoiding reprocessing of non-overlapping pixels while ensuring image quality through proper handling of overlapping regions.

AI summary
Methods, systems, and devices for graphics processing are described. A device may receive an image including a set of pixels. The device may render a first subset of pixels in each bin of a set of bins during a first rendering pass, and defer rendering a second subset of pixels and a third subset of pixels in each bin of the set of bins during the first rendering pass. The second subset of pixels may include edge pixels and the third subset of pixels may be between the first subset of pixels and the second subset of pixels. The device may render the second subset of pixels and the third subset of pixels in each bin of the set of bins during a second rendering pass based on rendering the first subset of pixels. The device may then output the image based on the first and second rendering pass.
