By analyzing the motion of an input animation with limited length, our system could synthesize large amount of various motions to yield a composting scene animation with unlimited length by connecting the input motion pieces through smooth transitions based on a motion graph layer, which is generated by using randomized cuts and further analysis on time domain. The smooth transitions are obtained by searching the best path according to specified circumstances. Finally the result is optimized by repeatedly substituting animation subsequences. The user can interactively specify some physical constraints of the scene on keyframes, such as wind direction or velocity of flow, even one simple path for character to follow, and the system would automatically generate continuous and natural motion in accordance with them.
