As a part of eSIGN project owned by University of East Anglia,this paper investigates the first step of the transformation of synthetic motion data files between two avatars,namely transformation from original avatar(Visia3) to a transitional avatar(newV3).It is divided into two parts to realize the transformation of bone position and bone rotation.An algorithm which takes full advantage of vector operations is used to realize the conversion of bone length between two avatars,and a rule produced by observation is also used to decide on local position for each new bone.As far as conversion of bone rotation is concerned,two methods are provided: inverse kinematics method using two-link planar chains and vector mapping method.Eventually,transformation from Visia3 to newV3 is successfully realized.The effectiveness of above methods is checked by experiments.
