Preprocessing Training set: – Shape dependent – Pose dependent – SCAPE body models [Anguelov et al. 2005] Physically Simluation – Use OptiTex Software

Framework Shape deformation using shape training set Changing pose using rigid rotation Add wrinkles using pose training set Remove cloth interpenetration

Define a deformation variations in clothing shape on different people rigid rotation applied to clothing part p containing triangle t non-rigid pose-dependent deformation

Deformation Due to Body Shape Slove Dt Shape Training Set identity matrix

Rigid Part Rotation The SCAPE pose is given by the parameters Map it to the corresponding cloth part

Deformations Due to Body Pose Slove Qt use second order dynamics model Post Training Set identity matrix

Removing interpenetration Move the mesh outside the body Consider four terms – Cloth-body interpenetration – Smooth warping – Damping – Tightness Minimize the energy function – Iteration

Inspiration Separate the deformation into three steps Use some training set to generation the deformation This paper proposes supervised learning of garment parameters used for dressing any input human model in any pose, with highly detailed wrinkles. It decouples the learning of body shape, pose, and detailed wrinkles. The training data is obtained from an interactive dressing software.
