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 deformationvariations in clothing shape on different people
rigid rotation applied to clothing part p containing triangle t
non-rigid pose-dependent deformation
Rigid Part Rotation
• The SCAPE pose is given by the parameters• Map it to the corresponding cloth part
Deformations Due to Body Pose
Slove Qtuse 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.
