Fast Modeling System of Digital Plant for Virtual Education

Virtual education is widely used in many fields including agricultural training and popular science. Modeling technologies and software tools for content making of virtual educations about digital plant is shortages and it is an obvious limitation of relevant applications. We present a fast modeling technology and developed a system of digital plant for virtual education. The method depends on real geometric data of plant collected by three-dimensional device, and a template-based modeling algorithm is employed for rapidly reconstruction of complex plant organs. The system consists of several modules including data processing, knowledge management, geometric modeling, graphics support and user interface. The system supports users to make education content about digital plant. Finally, some typical applications are given and some future works are discussed.
