Abstract
Urban greening has been campaigned actively today. Climbing plants attract attention because they are suited for making green spaces along the wall of buildings. Particularly, model generation methods for climbing plants are useful for prediction and estimation of scenery after greening. This paper presents a model generation method considering behavior of sucker using growth simulation with L-system. First, the proposed method defines symbols meaning the structure of climbing plants, and sets rules of L-system considering behavior that is observed from real climbing plants. Second, the proposed method simulates the growth with rules to control branching along the condition of buds. Using the method of directed random walk, one of slate points is selected as the position of bud in three dimensional space. At the end of this paper, we compare between the results using this method and the growth of real climbing plants, and consider the results.
