Sketch-based wrinkle generation for three-dimensional virtual garment prototyping

Wrinkles and folds are the most important properties determining the style of garment. In this paper, we propose a sketch-based method to generate arbitrary wrinkle shapes for three-dimensional (3D) garment prototyping. The user is required to draw wrinkle strokes on the original garment model in the front view and the back view. These two-dimensional strokes are then transferred into 3D shapes in terms of mesh deformations including Loop subdivision, Laplacian mesh optimization, and mean-value encoding/decoding. Various examples have validated the effectiveness of our proposed method, which can be regarded as a novel approach in 3D garment prototyping.
