PerfectTailor: Scale-Preserving 2-D Pattern Adjustment Driven by 3-D Garment Editing.

Area of Science:

• Computer Graphics
• Geometric Modeling
• Apparel Design Technology

Background:

• Current 2-D sewing pattern modification methods often use uniform flattening for 3-D garment edits.
• This approach fails to account for localized pattern scaling (e.g., cuff shrinking) and industry design conventions like straight edges.

Purpose of the Study:

• To develop an advanced pattern adjustment method for 3-D garment modifications.
• To address the limitations of uniform flattening in preserving local pattern details and design rules.

Main Methods:

• Utilizing the intrinsic scale matrix to handle nonuniform local scaling of 2-D sewing patterns.
• Implementing an as-original-as-possible geometric constraint to preserve boundary shapes when needed.
• Developing a prototype system with common garment alteration operations.

Main Results:

• The proposed method effectively modifies 2-D sewing patterns for 3-D garment edits.
• Demonstrated capability in handling local scaling and respecting design conventions through various alteration examples.
• Preservation of original pattern features and boundary integrity is achieved.

Conclusions:

• The new pattern adjustment method offers a more sophisticated approach to 3-D garment editing.
• This technique improves accuracy and adheres to industry standards, enhancing digital garment design workflows.
