We describe a venation skeleton-driven method for modeling and animating plant wilting. The proposed approach uses a representation of a three-dimensional skeleton for a leaf blade. Firstly, the leaf skeleton is used to generate a detail mesh for the leaf surface, and a venation skeleton is also generated interactively from the leaf skeleton. Each vein in the venation skeleton consists of a segmented vertices string. Secondly each vertex in the leaf mesh is banded to the nearest vertex in the venation skeleton. We then deform the venation skeleton by controlling the movement of each vertex in the venation skeleton by rotating it around a fixed vector. Finally the leaf mesh is mapped to the deformed venation skeleton, as such the deformation of the mesh follow the deformation of the venation skeleton. We apply our techniques to simulate wilting plant leaves resulted from biological response. © 2008 Springer-Verlag Berlin Heidelberg.
