Engineering Contradiction Analysis
1Volume of moving object
If traditional 3D display techniques are used, then holographic imagery can be displayed, but the system size becomes large and computational speed becomes slow
Solution Approach 1:
The patent segments the 3D object representation into primitives (geometric shapes) and further into vertices, with each element having unique identifiers. This segmentation allows for efficient memory addressing and parallel processing of different object components, reducing overall system complexity and computational burden while maintaining holographic display capability
Solution Approach 2:
The patent performs preliminary actions by pre-associating vertex identifiers with vertex data and primitive identifiers with vertex identifiers during data preparation. This pre-processing organizes the data structure before hologram generation, enabling faster retrieval and computation during actual display operations, thus improving computational speed without increasing system size
2Manufacturing precision
If high-quality 3D rendering is achieved, then image quality improves, but computational complexity and processing time increase
Solution Approach 1:
The patent changes the parameter representation by using identifier-based referencing instead of storing complete data sets. Vertex identifiers and primitive identifiers serve as compact parameters that reference detailed vertex data, reducing memory requirements and computational complexity while maintaining the precision needed for high-quality 3D rendering through efficient data retrieval
3Productivity
If efficient data manipulation is implemented, then processing speed increases, but memory management complexity increases
Solution Approach 1:
The patent creates a logical copy mechanism through identifier systems where vertex identifiers copy the essential reference information needed to access vertex data, and primitive identifiers copy the structural relationships. This copying approach enables fast data access and manipulation without duplicating entire data sets in memory, improving processing speed while keeping memory management manageable through reference-based addressing

AI summary
Methods, apparatus, devices, subsystems, and systems for holographically displaying three-dimensional objects are provided. In one aspect, a system includes a display and a controller coupled to the display. The controller is configured to: obtain primitive data of a plurality of primitives corresponding to an object, the primitive data indicating an overlap between adjacent primitives of the plurality of primitives; generate control signals for a plurality of display elements of a display using the primitive data of the plurality of primitives; and transmit the control signals to the display to modulate the plurality of display elements of the display based on the control signals.
