Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-quality light probes are generated throughout the virtual environment, then lighting effect quality is improved, but computational cost increases excessively
Solution Approach 1:
The patent applies local quality by determining a first region of the light probe based on predetermined conditions and storing light information at higher resolution in this first region than in a second region. This ensures high lighting quality in salient areas while reducing computational cost in less important areas, directly resolving the contradiction between light probe quality and computational expense
2Manufacturing precision
If light probe quality is increased, then lighting realism is improved, but specialized hardware is required
Solution Approach 1:
By implementing variable resolution storage where different regions of the light probe use different resolutions based on their importance, the patent achieves high quality lighting effects in critical areas without requiring specialized hardware throughout the entire system, thus reducing device complexity while maintaining lighting realism
3Measurement precision
If high resolution light information is stored in all regions, then lighting accuracy is improved, but memory requirements increase
Solution Approach 1:
The patent stores light information at higher resolution in the first region determined by predetermined conditions and at lower resolution in the second region, thereby maintaining high lighting accuracy in salient areas while significantly reducing the total memory requirements for storing light probe data
