Compared with visual effects in movies or full CG animations, Mixed-Reality based content production, a technique to overlap CG image with real world scene, demands more strict real-time representation and consistency with real environment. Natural phenomena are sometimes too complicated to describe in MR environment by physical modeling. We pick up "Falling Natural Objects" such as cherry blossoms, autumn leaves and snow to represent for stage effects. We proposed an effective method to approximate movements of fluttering natural objects by normal random walk. A simulation confirmed that the proposed method was also adaptable to wind change and different CPU load to represent various polygon size objects.
