Study on digital style design - Development of basic system for grain pattern design

In this paper, a novel approach for designing grain patterns based on digital technology is proposed. A digital tree is raised according to weather data such as daylight hours, precipitation, and temperature obtained from public organizations, and grain patterns are then formed as the cross section patterns generated by cutting the trunk of a digital tree. In order to simulate tree growth, digital trees are constructed as an electric charge model in consideration of dendrological characteristics and environmental conditions. A basic system based on the proposed method is developed and it enables one to make grain design as the cross section patterns of various types of digital trees which are obtained by changing growth conditions such as the growth period, the growth location and the slope angle of a growth place.
