Ray Tracing Frame Rendering via Checkerboard Region Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ray tracing techniques for rendering sequences of frames are computationally intensive, making them unsuitable for lower-powered devices and requiring significant processing resources, especially with the increasing use of higher resolution displays.
Innovation Solution
Implementing a checkerboard rendering technique where only a subset of regions in each frame are newly generated using ray tracing, with the remaining regions' output data derived from previously generated data from preceding frames, allowing for reduced computational load while maintaining realistic image quality.

Engineering Contradiction Analysis
1Manufacturing precision
If ray tracing is used to render all regions of each frame, then image quality and realism are improved, but computational processing requirements increase significantly
Solution Approach 1:
The frame is divided into multiple regions, and only a subset of these regions is rendered using ray tracing in each frame. This segmentation allows the computational load to be distributed across multiple frames while maintaining the visual quality benefits of ray tracing in key regions.
Solution Approach 2:
Ray tracing is applied periodically to different regions across successive frames rather than to all regions in every frame. This periodic application reduces the overall computational processing requirements while still providing ray-traced image quality in various regions over time.
2Manufacturing precision
If ray tracing is applied to high resolution displays, then image realism is improved, but processing intensity increases significantly
Solution Approach 1:
Instead of applying ray tracing to the entire high resolution display, the method applies it partially to only certain regions of the frame. This partial action maintains the realistic image quality benefits where needed while avoiding the excessive processing intensity that would result from full-frame ray tracing at high resolutions.
3Manufacturing precision
If full ray tracing is used for each frame, then rendering quality is improved, but processing time and resource consumption increase
Solution Approach 1:
The rendering process is segmented across multiple frames, with different regions receiving ray tracing treatment in different frames. This segmentation reduces the processing time required for each individual frame while ensuring that all regions eventually receive the quality benefits of ray tracing.
Solution Approach 2:
The method uses previously generated ray-traced data from prior frames to inform current rendering decisions. This preliminary action allows the system to leverage past computational work, reducing the need to recalculate ray tracing for all regions in every new frame.

AI summary
A data processor renders a new frame of a sequence of frames by, for each one of a subset of set of a plurality of regions of the new frame, newly generating output data for data elements in the region in respect of the new frame using a ray tracing process, and by deriving output data for data elements in each remaining region of the set of a plurality of regions of the frame based on data generated previously in respect of a preceding frame.
