Garment Refitting for Digital Characters

Original Video: vimeo.com/4322...
We present a new technique to refit garments between characters of different shapes. Our approach is based on a novel iterative scheme that alternates relaxation and rebinding optimizations. In the relaxation step, we use affine-invariant coordinates in order to adapt the input 3D garment to the shape of a target character while minimizing mesh distortion. In the rebinding step, we reset the spacing between the refitted garment and the character body controlled by user-prescribed tightness values. Our method also supports additional constraints that encode the spatial and structural arrangement of multi-layers, seams, and fold-overs. We employed this refit tool in Pixar's feature film \emph{Soul} to transfer garment pieces between various digital characters.
