Sewing pattern to 3D clothes

How to build a 3D model of clothes from a pattern? Any advice and suggestions would be very helpful.

If you have a list of all vertices/points, you can use THREE.ShapeUtils.triangulateShape to create a 2d mesh with a list of contour points and holes.
Or if you have an SVG, use SVGLoader to parse paths to triangulate.

What is you use case? If you’re looking to create a 3D model the best solution is to create it in a modeling software and export it to GLTF to use in your three.js scene.
If you’re looking to dynamically generate a 3D mesh based on your 2D sewing pattern, some more information on how the 2D patterns are created and an example of how they would look as 3 d objects would be helpful.
