摘要：Japanese ivy is receiving attention as green walls for solving the urban heat-island effect. Computer graphics are very useful for the evaluating the landscape of buildings covered by ivy, and thus, methods for creating computer-graphics models for climbing plants have been proposed. However, they have problems such as crowded branches and the ivy attaching to window glass, which are different from the actual growth of ivy. In this paper, a novel growth model is proposed that includes the effects of phototropism and the attachment strength by considering the material of walls. The method generates models of Japanese ivy that covers buildings, and it improves the density of the leaves and branches and represent growth around windows. The results of simulations with the proposed method showed that the method offers a more realistic landscape simulation of Japanese ivy covering buildings compared with the conventional method.
