Engineering Contradiction Analysis
1Productivity
If volumetric data is processed using traditional hierarchical file formats, then the data can be stored and accessed, but the processing becomes computationally expensive and time-consuming due to large memory overhead and unbalanced allocations
Solution Approach 1:
The patent segments volumetric data into discrete volumetric frames organized in a flat file format, where each frame is independently structured with consistent memory allocations. This segmentation eliminates the hierarchical overhead and enables efficient parallel processing of individual frames, directly improving rendering speed while reducing processing time.
Solution Approach 2:
The patent changes the fundamental parameter of data organization from hierarchical structures to a flat, uniform structure. By standardizing memory allocations and eliminating nested hierarchical levels, the system achieves balanced memory usage and reduced computational overhead, resolving the contradiction between productivity and processing time.
2Reliability
If volumetric data is processed in traditional formats, then complete data representation is achieved, but large memory overhead causes unbalanced allocations making it computationally expensive
Solution Approach 1:
The patent applies homogeneity by creating a uniform flat file format where all volumetric frames have consistent memory allocations and identical structural parameters. This eliminates the unbalanced allocations and complexity associated with hierarchical formats, while maintaining complete data representation through systematic organization of all volumetric frames in the standardized structure.
3Speed
If real-time rendering is attempted with traditional volumetric formats, then interactive applications can be supported, but the large computational overhead makes it difficult to meet real-time requirements
Solution Approach 1:
The patent performs preliminary organization of volumetric data into the flat file format with pre-defined memory allocations and uniform structures. This preliminary action eliminates the need for complex runtime memory management and hierarchical traversal, enabling real-time rendering with reduced computational resource consumption by preparing the data structure in advance for efficient processing.
