An Interactive System on Plant Modeling

As a useful tool and an important topic in computer graphics,method plant modeling has been employed for learning the structure and growth of plants.In this paper,an interactive plant modeling system based on graphics is designed for user to model various kinds of plants.The branch modeling is decomposed into two parts by the system.Firstly,an iterative method is used to draw different branches,and secondly a global algorithm is presented to shape the plants with overall silhouette and density.The user can change the parameters in the process of modeling by an interactive interface.Our system also supports a large number of leaf models generated by plant morphology knowledge,where the user can flexibly select any model to use or add new model into the system.The manipulation to the system is portable,and the plant models created by the system are quite realistic.
