The complexity of the geometry and topological structure of 3D trees not only makes the construction of realistic 3D tree models very complex but also increases data for the points and the faces saved in these model files. As to the complexity of constructing 3D trees and the large volumes of model data

we propose a construction method of lightweight 3D tree models supporting skeleton personalized editing in this paper. Based on extracting skeleton structures of existing trees models

this method can personalize 3D tree models through the interaction to generate a new frame structure

and adopts branches and crown simplification to realize the lightweight construction of trees models. The method can quickly create lightweight tree models that will reduce the visualization rendering time of 3D tree models as well as personalized edits to design the topological structure of the trees by using skeletons that increase the external form diversity of the same tree varieties. The applications show that the construction method of lightweight 3D tree models can not only build 3D tree models with different external forms

but also enable simplified 3D tree models to be visualized in wireless networks

mobile terminals

and other resource-limited circumstances.
