1Productivity
If traditional display data processing methods are used for rotatable 3D display devices, then display quality can be maintained, but processing complexity and resource consumption increase significantly
Solution Approach 1:
The patent performs meshing operations on the image model in advance, before the actual display process. By pre-processing the 3D model into a mesh structure with vertices, edges, and faces, the system prepares display data that can be efficiently rendered at different rotation phases without repeating complex calculations during runtime.
Solution Approach 2:
The patent divides the image model into discrete triangular faces and vertices, creating a segmented mesh structure. This segmentation allows the system to process and render only the necessary portions of the model at each display phase, reducing the computational burden compared to processing the entire model continuously.
2Manufacturing precision
If meshing operations are performed at each display phase, then display accuracy is maintained, but processing time and resource utilization increase
Solution Approach 1:
The meshing operation is executed once in advance to generate the triangular face structure, rather than performing meshing at each display phase. This preliminary action ensures display accuracy is maintained while avoiding repeated computational overhead during the actual display process.
Solution Approach 2:
The patent creates a mesh representation (a simplified geometric copy) of the original image model. This mesh copy retains the essential geometric information needed for accurate display at different phases, allowing the system to work with the simpler mesh structure instead of the complex original model during rendering.
