Abstract:
We show how to transfer the motion of cloth from a source to a target body. The obvious method is to add the displacements of the source cloth, calculated from their position in the initial frame, to the target cloth; but this can result in penetration of the target body, because the shape of the target body. To overcome this problem, we compute an approximate source cloth motion, which maintains the initial spatial relationship between the cloth and the source body; then we obtain a detailed set of correction vectors for each frame, which relate the exact cloth to this approximation. We then compute the approximate target cloth motion in the same way as the source cloth motion; and finally we apply the detail vectors that we generated for the source cloth to the approximate target cloth, thus avoiding penetration of the target body. We demonstrate the retargeting of cloth using figures engaged in dance movements.
