Abstract: Modeling and simulation of virtual plant should be efficient and realistic. Many existed modeling and simulation methods have been focused on the static organs of plant models, in which foliage are modeled by simple 2D polygons that the thickness and the motion of leaves are neglected. Such models are far from the realistic ones. A new modeling and animation method of broadleaf plants is proposed. According to the natural properties of broadleaf plants this method uses the similarity of the growth structure of leaves and stems in the modeling process. This method also takes the thickness of leaves into consideration in building 3D leaf model. In particular, by introducing the force constraint between midrib and parallel venation, the dynamic simulation of leaves can be vividly performed. Experiments show that the proposed method can simulate the leaf's motion effectively and realistically.
