Study on digital style design development of grain pattern design system

In this paper, a novel approach for designing grain patterns based on digital technology is proposed. In the previous paper, the basic tree growth model was developed by investigating the basic growth-features of trees and the responding growth features on growing environment conditions: daylight hours, precipitation, temperature, and the ground inclination angle. The basic tree growth model was constructed by using the electric charge method which can easily represent the trunk and branches and could generate a variety of woodgrain patterns by changing the growing environment conditions. The tree model developed in the previous paper enables to reproduct the trunk and branches. However, it is required to make a more realistic digital tee model. In this paper, in order to generate more natural woodgrain patterns which can be used for industry design, the method to construct a more precise digital trees model is proposed. A design system of grain patterns is developed based on the proposed method. The digital woodgrain patterns generated by the system are evaluated.
