風による柔軟物体の揺らぎ運動を表現する風乱流モデルに関する研究

摘要

A series of natural wind models have been developed since the 1960s to facilitate the study of wind engineering problems. In this paper, we present a study on wind turbulence models from the field of engineering and indicate their applicability in computer animations for simulating a variety of motions and the behaviors of flexible objects in windy conditions. We describe theoretical aspects of wind turbulence based on measurements of actual winds and their mean direction. We also describe a simple yet visually convincing simulation of wind fields using our proposed wind models generated from actual wind data. The efficiency and practical utility of the wind field model is implemented in a simulation of grass blowing in the wind.
