An Interactive plant pruning system based on GreenLab model: Implementation and case study

Functional-structural plant models (FSPMs) attract much attention from researchers in the area of both plant science and computer science. Such models make it possible to have interaction between human being and virtual plants. However, attempts of simulating pruning are still few, and obtaining self-organized reaction as in real plants remains a challenge. In this paper, we present an interactive system of plant pruning based on GreenLab model, where bud dormancy can burst into branches by modified source-sink balance after pruning. With the mechanism feedback in the model, users can change the form and growth of plant via different pruning policies. Virtual experiments show that our system gives realistic result, and can potentially serve for applications in agronomy, education and virtual reality.
