Simulation of Chinese Fir´s Geometrical Modeling and Growth Model Based on Morphological Characters

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. A number of methods have been proposed for generating trees, But these methods could not accurately simulate the appearance changes in the growth process of trees. The paper presents an interactively parameterized modeling method based on the morphological characters of Chinese fir and the results testify our method can simulate Chinese fir well.
