Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complete distortion model is applied to computer graphics, then the accuracy of lens distortion simulation is improved, but the computational latency increases and interactivity deteriorates
Solution Approach 1:
The distortion model is segmented into a reduced sample set of key parameters rather than processing the complete model. This segmentation allows the system to capture essential distortion characteristics while eliminating redundant computational elements, thereby reducing latency while maintaining acceptable accuracy for interactive applications.
Solution Approach 2:
The patent applies partial action by using only the necessary portion of the distortion model (reduced sample set) rather than the complete model. This partial application is sufficient for achieving the desired distortion effect in real-time interactive scenarios, sacrificing minimal accuracy for significant gains in processing speed and interactivity.
2Productivity
If a reduced sample set distortion model is used, then computational efficiency and interactivity are improved, but the accuracy of distortion representation may be reduced
Solution Approach 1:
The patent changes the parameters of the distortion model by selecting a reduced sample set of key parameters that most significantly impact distortion appearance. This parameter selection transforms the complete model into a streamlined version that maintains visual fidelity while improving computational efficiency for real-time processing.
3Ease of operation
If distortion model is applied in real-time during user interaction, then user experience and interactivity are improved, but processing complexity increases
Solution Approach 1:
The distortion model is prepared and reduced to a sample set in advance before real-time interaction begins. This preliminary preparation eliminates the need for complex real-time calculations during user interaction, allowing the system to apply pre-computed distortion parameters efficiently while maintaining high interactivity and user experience.
Data Source
AI summary
A system includes a computing device that includes a memory for storing one or more computer graphics, and a graphics distorter. The graphics distorter applies a distortion model to the computer graphic to produce a distorted version of the computer graphic, while substantially simultaneously allowing user interactions with the computer graphic. The applied distortion model represents lens distortion.
