Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for compressing and decompressing three-dimensional scene representations are inefficient and do not effectively balance memory usage with image quality, particularly in real-time rendering applications.
Innovation Solution
A method that identifies discontinuities in three-dimensional scene properties and stores their positions and measures as a compressed representation, suitable for implementation on graphics processing units (GPUs) to achieve high compression ratios while retaining important information for accurate image rendering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the full uncompressed representation of the three-dimensional scene is stored, then the image quality and rendering accuracy are maintained, but the memory occupancy and data transmission requirements increase significantly
Solution Approach 1:
The patent extracts only the essential discontinuity information from the full scene representation. By identifying and storing only the position parameters and property measures at discontinuity locations rather than all scene data, the method achieves significant compression while preserving the critical information needed for accurate rendering.
Solution Approach 2:
The patent changes the representation parameters from storing all scene position-parameter pairs to storing only discontinuity position parameters and their corresponding property measures. This parameter transformation enables the compression of the scene representation while maintaining the ability to reconstruct the essential scene properties for rendering.
2Manufacturing precision
If more scene information is retained in the compressed representation, then the rendering quality improves, but the compression ratio decreases
Solution Approach 1:
The patent extracts precisely the necessary information for high-quality rendering - the discontinuity positions and property measures - without including redundant data. This selective extraction achieves both high compression ratios and maintains rendering quality by capturing only the essential features that define scene properties.
Solution Approach 2:
The patent applies local quality by focusing computational and storage resources on the discontinuity locations where scene properties change significantly, rather than uniformly processing all scene data. This approach ensures that rendering quality is maintained at critical locations while achieving compression in regions where properties are more uniform.
3Quantity of substance
If traditional compression methods are used, then the memory usage is reduced, but the rendering accuracy and image quality deteriorate
Solution Approach 1:
The patent extracts the critical discontinuity information that traditional compression methods would discard or heavily compress. By specifically identifying and preserving discontinuity position parameters and property measures, the method maintains rendering accuracy while achieving memory reduction comparable to traditional compression techniques.
4Quantity of substance
If the compression and decompression process is made more complex to achieve better compression ratios, then the memory efficiency improves, but the processing time and computational complexity increase
Solution Approach 1:
The patent performs preliminary identification of discontinuity locations during the compression phase, organizing the data in a structure that facilitates efficient decompression. By pre-processing the scene data to identify and categorize discontinuities, the method reduces the computational burden during decompression and rendering, achieving both memory efficiency and acceptable processing times.

AI summary
CLEAN COPY OF THE ABSTRACT AS AMENDEDDisclosed are methods and systems for compressing a representation of a three-dimensional scene and decompressing a compressed representation of the scene. Compressing a representation of the scene may comprise detecting a subset of position parameters included in the scene, which are indicative of positions of discontinuities in measures of a property of the scene; and storing the subset of the plurality of position parameters and the measures of the property of the scene corresponding to the subset of the plurality of position parameters as a compressed representation of the scene. A compressed representation of a three-dimensional scene may comprise first measures of a property of the scene corresponding to a plurality of first position parameters indicative of first positions in the scene. Decompressing the compressed representation of the scene may comprise determining second measures of the property of the scene.
