Abstract

Abstract:

The three-dimensional visual model of sympodial branching trees was simulated. Pointed out descriptive index of sympodial branching trees, taking Sophora japonica as an example, by making branch fall into primary and secondary branch, did some statistical analysis of morphological parameters like branch diameter, elevation angle and branch length. Then reached the conclusion that the mean value of primary branch diameter was greater than secondary branch diameter, while the elevation angle and branch length of primary branch was less than secondary branch.The distribution of elevation angle was ideally normal, and ranged from 20° to 40°, and branch length distributed in 20-40 cm. Based on IFS algorithm, presented a data structure that was suitable for expressing sympodial branching morphological characteristics, and specifically pointed out the real meaning of IFS parameters corresponding to sympodial branching structure, stated the method of constructing sympodial branching trees model, and built the three-dimensional visual model of sympodial branching trees in the end. The constructed tree model was in line with the sympodial branching morphological characteristics, and indicated that it could achieve expressing the basic morphological structure of sympodial branching trees.

Key words: sympodial branching, IFS, visualization
