3D Avatar Clothing Pattern Arrangement via Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clothing pattern arrangement systems limit the flexibility of placing patterns on 3D avatars due to pre-defined body locations and result in unconformity and self-intersection issues when projecting patterns onto planar or cylindrical surfaces.
Innovation Solution
A method and system that allow users to freely select target locations on a 3D avatar for 2D clothing patterns, representing them as 3D patterns by solving optimization functions to determine vertex positions and ensure tight wrapping, reducing self-intersection and enhancing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-defined body locations are used for pattern arrangement, then the system complexity is reduced and operation is simplified, but the flexibility and adaptability of placing patterns on 3D avatars is limited
Solution Approach 1:
The system transitions from static pre-defined body locations to dynamic free-selection of target locations on the 3D avatar. Users can dynamically select any location on the avatar surface, and the system dynamically adjusts the pattern arrangement and 3D representation accordingly, enabling both ease of operation through automated processes and high adaptability through flexible location selection.
2Ease of manufacture
If patterns are projected onto planar or cylindrical surfaces, then the manufacturing and display process is simplified, but self-intersection issues occur and conformity with the 3D avatar is poor
Solution Approach 1:
The system transitions from projecting patterns onto 2D planar or cylindrical surfaces to directly representing 2D patterns as 3D clothing patterns that wrap around the 3D avatar in three-dimensional space. This dimensional transformation eliminates self-intersection issues and improves conformity with the avatar's complex 3D geometry, while the automated 3D representation process maintains manufacturing simplicity.
3Device complexity
If fixed target locations are used on the 3D avatar, then the system complexity is reduced, but the ability to achieve tight wrapping and reduce self-intersection is compromised
Solution Approach 1:
The system replaces the mechanical constraint of fixed target locations with an automated computational optimization system. The system uses algorithms to automatically determine optimal target locations and adjust pattern arrangements to achieve tight wrapping and eliminate self-intersection, maintaining low device complexity while significantly improving wrapping quality and reliability.

AI summary
A method and a user device for arranging clothing patterns may be provided. A first user instruction may be received. The first user instruction may be used for selecting a first target location from a two-dimensional (2D) clothing pattern and allocating the 2D clothing pattern to a second target location on a three-dimensional (3D) avatar. In response to the first user instruction, the 2D clothing pattern may be represented as a 3D clothing pattern that warps around the 3D avatar at the second target location.
