Abstract:

With the increased attention on simulations of trees and forest ecosystem, the visualization of plants quickly becomes the combinative development trend of graphics and forestry. The simulation of trees is one of the latest topics of forestry visualization. Because Pinus massoniana is a special main forestation species and it has been researched by many scholars, according to the observation data of different year of Pinus massoniana, the paper presents a interactively parameterized modeling method based on the shape of Pinus massoniana, and simulates different geometrical models of several years. Through the experiments, this method testfies that it can simulate Pinus massoniana well.

Key words: Pinus massoniana, geometry modeling, morphological characters, growth pattern
