Research And Development, Based On Physical Constraints Dance Auxiliary Choreography

The folk performance art is the important part of tradition culture in our country. However, because of the rapid development of society and economy, some folk performances were confronted with disappearance. The protection of folk performance art and the applying digital technology to the protection work should to be paid more attention. Based on the existing research on folk dance digitalization and assisted arranging, we analyze the problem in existing work and the new requirement in dance arrangement. The works in this paper are:1 , We design the dance segments database, implement the local editing method on joints and provide more convenient user interface. The local editing using the displacement mapping and quaternion sphere linear interpolation.2, Our primary work implementing an efficient method for touching up edited motions to improve physical plausibility. We divide the edited motion into ground and flight stages and enforce appropriate physical laws. For ground stages, correcting the ZMP to make it inside of the support polygon. For flight stages, making the center of mass follow a parabolic trajectory and total angular momentum of body conserved. After the balance adjustment, we add the angular momentum adjustment.
