Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If floating point representations are used for vertex characteristics, then precision is maintained, but data size increases transmission and rendering time
Solution Approach 1:
The patent segments the floating point representation into multiple fixed point representations with different precision levels. Each segment corresponds to a different significance level, allowing progressive transmission from most significant to least significant values. This segmentation enables early rendering with coarse precision while maintaining the option to refine later.
Solution Approach 2:
The patent changes the parameter representation from floating point to fixed point format. This transformation allows the same numerical value to be represented with different precision levels by adjusting the fixed point position, enabling progressive refinement without requiring full precision from the start.
2Manufacturing precision
If full resolution mesh is transmitted first, then rendering quality is high, but transmission time increases
Solution Approach 1:
The patent performs preliminary action by transmitting and rendering the most significant fixed point values first, which provide a coarse but immediate representation of the 3D content. This preliminary rendering allows users to see recognizable geometry quickly, while less significant values are transmitted and applied subsequently to refine the quality.
Solution Approach 2:
The patent implements dynamic rendering quality by allowing the precision level to change over time. The system starts with lower precision fixed point representations for quick initial rendering, then dynamically increases precision by incorporating less significant values as they are transmitted, adapting to available time and bandwidth.
3Productivity
If mesh compression techniques are used, then transmission efficiency improves, but content richness is reduced
Solution Approach 1:
The patent changes the precision parameter of vertex characteristics from full floating point to progressive fixed point representations. This parameter change enables transmission efficiency by sending less significant values later, while preserving content richness by maintaining the full precision representation in the final rendered output.
4Manufacturing precision
If manual supervision is used to generate mesh series, then content quality is controlled, but processing time and complexity increase
Solution Approach 1:
The patent implements self-service by automatically generating the series of fixed point representations from the original floating point data without requiring manual user intervention. The system autonomously determines the segmentation into different significance levels and generates the progressive mesh series, eliminating manual supervision while maintaining quality control through the structured fixed point transformation.

AI summary
Transmission and configuration of three dimensional digital content is described. In one or more implementations, three-dimensional digital content is received having a three-dimensional mesh of a plurality of vertices. Each vertex includes a definition of a characteristic of the three-dimensional content. The definition of the characteristic is transformed for each vertex from a floating point representation to a fixed point representation. The fixed point representation includes a plurality of values that have different amounts of significance in defining the characteristic, one to another. The plurality of values is indexed of the fixed point representation of the definition of the characteristic. The indexing is based on the different amounts of significance, one to another. Output of the three dimensional digital content is controlled based on the indexed plurality of values.
