Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image generation technologies face challenges in reducing storage and processing burdens due to inefficiencies in representing and rendering complex three-dimensional models, particularly with traditional methods like triangle strips and triangle fans, which result in increased data storage and processing requirements.
Innovation Solution

Engineering Contradiction Analysis
1Quantity of substance
If traditional triangle strip encoding is used to represent three-dimensional meshes, then the mesh can be rendered, but redundant data and degenerate triangles increase storage requirements and processing burden
Solution Approach 1:
The patent extracts and removes redundant data and degenerate triangles from the triangle strip encoding. By identifying and eliminating unnecessary vertices and triangles that do not contribute to the visual representation, the encoding achieves both reduced storage requirements and improved processing efficiency, as the rendering system processes only essential geometric data
Solution Approach 2:
The patent changes the encoding parameters by introducing optimized vertex indexing and triangle strip construction methods. By modifying how vertices are referenced and how triangle strips are generated, the system reduces the quantity of data stored while maintaining rendering quality, thereby improving processing efficiency without sacrificing visual fidelity
2Manufacturing precision
If detailed three-dimensional models are generated with high image quality, then visual realism is improved, but storage and processing burden increases
Solution Approach 1:
The patent segments the three-dimensional mesh into optimized triangle strips with systematic vertex indexing. By dividing the complex mesh into manageable strips and applying consistent encoding rules, the system maintains high geometric precision for realistic rendering while reducing the overall processing burden through structured, efficient data organization
Solution Approach 2:
The patent performs preliminary optimization during the encoding phase by pre-identifying and removing redundant vertices and triangles before rendering. This advance processing reduces the complexity of data that needs to be handled during actual rendering operations, allowing high-quality detailed models to be stored and processed more efficiently
