Method of Tree's Interactive and ParameterizedModeling Basedon V irtual ForestManagement

In view of tree arch itecture, the traditional geometric modeling techniquew as comb ined w ith tree s mo rpho log ic structure so that tree s interactive and parameter ized modeling method w as introduced in this paper. Threekinds of parameters, truncks, branchs and leaves, w ere used to describe trees, then some modeling ru les w ere putforw ard, and a tree classification system w as bu il.t Therefore, the forestmanager could use their fam iliar parametersto construct three-d imensional geom etricmode ls o f different tree speciesw ith d ifferen t geometric characterist ics, and,themode ls for different g row th stage w ere achieved. The modelw as simple and its appearance w as lifelike, and itcould express the spatia l construction o f the tree adequate ly.
