To those animators, it is quite difficult to realize the smooth movement of objects by matching the spatial data points with continuous and smooth curves and planes in computer graphics. In this paper, the accelerated motion of curves and planes are controlled by simple manipulation of a set of control parameters or the real-time interaction between animators and the scenarios created by dynamic simulation. And all the objects discussed in this paper are with the forms of rigid links of trees linking at joints in this paper. Motion equations are expressed in the coordinate centering on the joint, and are to be resolved by effective timing-technique which is increased linearly with the growth of the number of links.
