Abstract: Systems and methods are provided for generating custom garment patterns for producing clothing sized to fit any newly input human body representation. A set of reference sample bodies may be selected for which custom designed garment patterns are then obtained. Once reference patterns are obtained, a custom garment pattern for a particular new body may be automatically created by blending two or more of the reference patterns. For example, the neighboring reference bodies to the new body may be identified within a low-dimensional embedding space, and interpolation of garment parameters for the previously designed garment patterns for these reference bodies may be performed to produce a custom garment pattern.

Abstract: Systems and methods are provided for improved 3D garment draping simulation. A garment pattern may be obtained that includes a number of flat, 2D garment panels designated to be connected at seam lines. Triangulated versions of each of the 2D garment panels may then be positioned in 3D virtual space relative to a 3D model of a human body, such that one or more annotated points on each triangulated garment panel are aligned with a corresponding labelled point or region on the 3D body. A warped 3D garment mesh may then be generated by repeatedly applying geometric manipulations to the triangulated garment panels to connect their corresponding seam lines without causing collisions between the triangulated garment panels and the 3D body. This warped 3D garment may then be provided as input to a physics-based draping simulator.

Abstract: Systems and methods are provided for generating a flat garment pattern and/or 3D mesh representation of a garment from one or more images depicting the garment laid flat or hung up. A system may obtain both a front image depicting a front view of a garment and a back image depicting a back view of the garment. A front and back silhouette of the garment may then be generated, which may include segmenting the garment depiction from background image content. A parametric representation of the garment may then be generated based on the front and back silhouettes, which may be implemented by iteratively optimizing, using differentiable rendering techniques, a garment representation within a parametric garment space previously learned for the particular garment type. A 3D mesh garment representation may then be generated based on the parametric representation, from which a flat sewing pattern may subsequently be generated if desired.
