In this paper, we proposed an ecient and effective animation techniques for
virtual trees modeled with L-system. The method proposed in this paper plau-
sibly animates the virtual trees based on hierarchical shape matching (HSM)
without any complex dynamic equations. The HSM is an improved version of
usual shape matching. In this approach, the object is divided into small clusters,
and each cluster is locally animated with the shape matching while the global
shape is also adjusted in accordance with the original shape.
The proposed method can be easily exploited to animate various virtual trees,
and the computational burden of the proposed method is relatively smaller than
those of the traditional approaches such as free form deformation or physically
based animation techniques. Moreover, the proposed method generates plausible
animation with numerical stability. The method proposed in this paper will be
successfully employed in interactive applications such as game.
