Abstract: The difficult problems existing in current virtual plant modeling software systems are analyzed, and then an efficient software system for plant-image simulations is designed and implemented based on the templates library of plant in this paper. The systematic framework, the establishment of templates library, the steps of creating 3D plants images, and the system interfaces are successively introduced. Finally, some examples are presented.
