Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data conversion is performed on the fly between different coordinate systems and color spaces, then the system can maintain flexibility in handling various data formats, but the rendering process speed decreases
Solution Approach 1:
The patent applies preliminary action by performing data conversion from object tree formats to GPU-specific formats (coordinates, colors, data types) in advance before rendering. This is achieved by creating an optimized graphics rendering tree that pre-processes and transforms all necessary data, eliminating the need for real-time conversion during rendering and thereby maximizing GPU execution speed while maintaining format flexibility
2Productivity
If specialized processing units like GPUs are used for graphics rendering, then processing efficiency is improved, but the complexity of data format conversion between CPU and GPU increases
Solution Approach 1:
The patent introduces an intermediary optimized graphics rendering tree that acts as a mediator between the CPU's object tree and the GPU's rendering pipeline. This intermediary structure performs all necessary format conversions, coordinate transformations, and color space adjustments, simplifying the interface between CPU and GPU while maximizing the specialized processing capabilities of the GPU
3Measurement precision
If real-time data conversion is performed during rendering, then data accuracy is maintained, but processing time increases
Solution Approach 1:
The patent applies preliminary action by performing all data conversions, coordinate transformations, and color space adjustments in advance during the creation of the optimized graphics rendering tree. This pre-processing ensures data accuracy is maintained while eliminating time-consuming real-time conversions during the actual rendering process, thereby reducing processing time

AI summary
A system creates a first set of objects in a first structure that describe a graphical scene. A second set of objects is created in a second structure based on the first set of objects in the first structure. The system also performs one or more of the following: i) converting coordinate values in a first coordinate system to coordinate values in a second coordinate system, ii) converting color values in a first color space to color values in a second color space, and/or iii) converting data having first data types or formats to data having second data types or formats, where the first data types or formats are different than the second data types or formats. The system further associates the converted coordinate values, color values and/or data types or formats with the second set of objects and enables a graphical processing unit to use the second set of objects for rendering the graphical scene.
