Engineering Contradiction Analysis
1Volume of moving object
If traditional 3D display techniques are used, then holographic imagery can be simulated, but the optical systems become large and complex
Solution Approach 1:
The patent segments the 3D object representation into primitives (geometric shapes) and further into vertices, allowing independent processing and storage of each component. This segmentation enables efficient memory management and processing while maintaining display quality.
Solution Approach 2:
The patent uses vertex buffers and index buffers to create efficient data copies and representations. Vertex data is stored in optimized formats with identifiers that reference specific geometric properties, allowing rapid retrieval and rendering without requiring complete object data in memory.
2Productivity
If computation speed is increased for high refresh rates, then display refresh rate improves, but processing complexity increases
Solution Approach 1:
The patent performs preliminary actions by pre-calculating and storing vertex data, primitive definitions, and their associations in optimized buffer structures before rendering. This preparation enables rapid frame generation at high refresh rates without increasing real-time processing complexity.
Solution Approach 2:
The patent extracts essential geometric information into separate vertex buffers and index buffers, removing unnecessary data from the main processing flow. This extraction allows the system to focus computational resources only on the critical data needed for high-speed rendering.
3Manufacturing precision
If image quality is improved with high efficiency, then display quality improves, but system complexity increases
Solution Approach 1:
The patent applies local quality by storing different types of vertex data (position, color, texture coordinates, normals) as separate attributes associated with specific vertex identifiers. This allows the system to optimize memory usage and processing by handling only the relevant attributes for each rendering operation while maintaining high image quality.
