Fig. 3.
Growth of a virtual tree
The animation result is shown in Fig. 4. For the animation, 211,812 vertices
and 4,975 clusters were used. As shown in the figure, the hierarchical shape
matching produced a plausible animation where thin branches and leaves move
more than thicker branches. The bending tendency of the branches, of course,
can be easily controlled in our method.
Fig. 4.
Animation with the hierarchical shape matching
The leaves could be easily detached from the tree as shown in Fig. 5. As shown
in the figure, the detached leaves float in the air and generate realistic wind and
tree interaction animation.
