A Method of 3D Garment Model Generation Using Sketchy Contours

This paper presents a method to reconstruct a 3D garment model from a sketchy garment contour, there are three features with our method: firstly, a reference model of 3D human is established by restricting the direction of the distance field (only direction along z-axis is considered), and it makes the computation of distance field much easier; secondly, an efficient mapping from 2D sketch to 3D garment is established by using the relative position between sketched garment contour and the outline of human projection; thirdly, the 3D garment model is constructed according to the mapping between garment grids and the grids of human model, and it ensure that loose part of garments can be constructed correctly. The experiment results prove that the proposed method can generate a garment surface constrained by sketch and adapted the underlying form of character model, and the process can perform in real time.
