An Applied Research on the SpeedtreeCAD-based Virtual Tree Modeling Technology

In order to explore the virtual tree holographic modeling,a research on SpeedtreeCAD,a software called plant modeling,was made,in which prunus padus was taken for example,the principle of editing the basic parameters of trees was applied as basis,the settings were edited in the four areas of framework,branch,leaf and effect of the model and the data of the model of the prunus padus in SpeedtreeCAD were obtained.The result showed that the tree model generated by SpeedtreeCAD has a high trueform,dynamic effect,fast rendering speed and easy maneuverability.Also,it is so excellently matchable as to be compatible with 3DMAX.And in the garden landscape designing,this model can be effectively used to guide the effect show of the plant arrangement and thus provides a very practical basis for the selection of gardening plant species
