Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If texture mapping is used to attach image data to three-dimensional object surfaces, then high-reality images can be achieved with fewer vertexes, but it becomes difficult to dynamically select and synthesize desired images onto specific surfaces in real-time
Solution Approach 1:
The patent segments the three-dimensional object into multiple polygons with unique identifiers, allowing independent texture mapping control for each polygon. This segmentation enables the system to selectively apply different image data to specific surfaces without affecting the entire object, thus achieving dynamic image selection while maintaining high-reality rendering through texture mapping.
Solution Approach 2:
The patent introduces dynamic control mechanisms that allow real-time switching of image data attached to polygon surfaces. By enabling runtime selection and assignment of image data to specific polygons based on timing and surface designation, the system transforms static texture mapping into a dynamic process suitable for live broadcasting and real-time synthesis applications.
2Measurement precision
If pre-synthesized images are used for broadcasting, then image quality can be maintained, but the system cannot respond to live broadcasting requirements where images need to be selected and synthesized in real-time
Solution Approach 1:
The patent performs preliminary organization of image data and polygon identification during the modeling phase, assigning unique identifiers to each polygon and pre-establishing texture coordinate systems. This preliminary preparation enables rapid real-time selection and synthesis during broadcasting without requiring complex processing at runtime, thus maintaining image quality while minimizing synthesis delay for live applications.
3Shape
If complex object shapes with repeated patterns are modeled using triangles or polygons, then three-dimensional representation is achieved, but the modeling process becomes difficult and time-consuming
Solution Approach 1:
The patent uses texture mapping to copy two-dimensional image data onto three-dimensional polygon surfaces, avoiding the need to manually model complex repeated patterns in three dimensions. By attaching flat image data to polygon surfaces through texture coordinates, the system achieves accurate representation of complex shapes and patterns without the computational complexity of creating detailed three-dimensional geometric models.
