Interactive Virtual Fruit Tree Pruning Simulation

Abstract

This paper proposed an interactive virtual pruning method for fruit tree. In this method, Unity3D - a common game development platform - was used as the implementation tool for the interactive virtual pruning simulation of fruit tree, including integrating 3D fruit tree and scissor into a virtual orchard scene, processing human-computer interaction and providing real-time feedback. Citrus tree was used as an example to test the proposed method. We simulated the pruning in small fruit stage and fruit picking in matured stage respectively. Experiment results show that this method can vividly simulate the pruning process and render the morphologic changes in the 3D tree model after pruning immediately. Combining with pruning rules, Unity3D should be a convenient and easy to implement tool for demonstrating fruit tree pruning techniques, training famers and so on.
