MiGumi: Making Tightly Coupled Integral Joints Millable

This dataset contains 30 traditional kigumi (wood joinery) joints with interactive shader-based visualizations. Our paper focuses on adapting these joints for CNC milling—transforming traditional designs with sharp internal corners into millable geometries that maintain tight coupling between parts.

For each joint, we provide multiple visualization modes:

• Full Joint mode: Explore the complete assembly sequence and see how parts fit together
• Per-Part modes: Examine individual components and the subtractive extrusions required to manufacture each part

Each joint is available in four variants:

• Base: The original traditional joint design without milling considerations
• Mill: Baseline approach using morphological opening only (ensures millability)
• ODF: Baseline combining opening with diff-flip operation (ensures tight coupling)
• Ours: Our method that jointly optimizes geometry for both millability and tight coupling
