Engineering Contradiction Analysis
1Ease of manufacture
If detailed lighting and color effect data is used to enhance user experience in 3D environments, then the quality and immersion of media content playback is improved, but the amount of data required for storage, transport, and processing increases significantly
Solution Approach 1:
The patent segments lighting effect data into multiple components: geometric representation data, position data, transform data, and color attribute data. Each component can be processed and transmitted independently, reducing the complexity of handling large datasets while maintaining the quality of lighting effects through structured decomposition of the data representation.
Solution Approach 2:
The patent employs parameter changes by using transform matrices to represent spatial relationships and by encoding color attributes in a compressed format. The transform data allows for efficient representation of 3D space without requiring explicit coordinate data for all points, reducing data volume while preserving spatial accuracy for lighting calculations.
2Adaptability or versatility
If comprehensive lighting control data is encoded to enable dynamic lighting effects, then the versatility and adaptability of lighting control is improved, but the complexity of data structure and processing increases
Solution Approach 1:
The patent creates a universal data structure that can represent various lighting scenarios and effects through a single standardized format. The geometric representation, position, transform, and color attribute components work together to support multiple lighting configurations, enabling the same data structure to handle diverse lighting control requirements without increasing complexity.
Solution Approach 2:
The patent introduces transform data as an intermediary between the geometric representation and the actual lighting calculations. This transform layer abstracts the complexity of 3D coordinate transformations, allowing lighting control systems to work with simplified reference frames while still achieving accurate lighting effects in the final 3D space.
