Solution Overview
Problem
Existing three-dimensional editing systems are cumbersome, inflexible, and require expert knowledge, limiting their ability to modify high-resolution models with complex details, and lack intuitive parameter editing tools.
Innovation Solution
A modification transfer system that utilizes semantic parameter handles to adjust implicit functions, transferring modifications from low-frequency, low-parameter models to high-frequency, high-resolution three-dimensional models while preserving unmodified regions, using scalar implicit function values and gradients to ensure precise and flexible editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing three-dimensional editing systems are used, then models can be modified, but the systems are cumbersome and require expert knowledge
Solution Approach 1:
The patent introduces an implicit function as an intermediary representation between the user's intuitive edits and the final three-dimensional model. Users interact with simplified implicit function parameters (e.g., adjusting a handle to change curvature), and the system automatically transfers these semantic modifications to the high-resolution mesh, eliminating the need for complex direct mesh editing tools while maintaining precision.
Solution Approach 2:
The system creates a simplified copy of the three-dimensional model in the form of an implicit function representation. This low-frequency, low-parameter copy captures the essential semantic structure, allowing users to edit it intuitively without dealing with the complexity of the original high-resolution model's detailed geometry.
2Adaptability or versatility
If existing editing systems are used, then models can be modified, but they are inflexible and cannot adapt to various shapes and resolutions
Solution Approach 1:
The implicit function serves as a universal representation that can describe various three-dimensional shapes and structures through a common mathematical framework. The same editing interface and implicit function operations can be applied across different model types and resolutions, providing flexible adaptation without requiring shape-specific tools or complex configuration.
3Manufacturing precision
If high-resolution models are edited directly, then detailed modifications can be made, but distortion occurs and editing becomes complex
Solution Approach 1:
The patent segments the editing process into two distinct stages: first, performing intuitive semantic edits on the simplified implicit function representation; second, transferring these edits to the high-resolution model. This segmentation allows precise control over the editing process while maintaining operational simplicity, as users never directly manipulate the complex high-resolution geometry.
4Adaptability or versatility
If procedural models with many parameters are used, then flexibility is achieved, but the number of parameters increases complexity
Solution Approach 1:
The system extracts and isolates the essential semantic parameters from the complex procedural model representation. By representing the model as an implicit function with a small number of meaningful parameters (e.g., curvature, thickness, position), the system maintains flexibility in shaping while eliminating the overwhelming number of parameters that would otherwise be required to control every detail of the three-dimensional geometry.
