B116 煙流の濃度と速度の写実的なインタラクティブ可視化手法

抄録

To establish a social consensus for disaster prevention, understanding of possible disasters is required. In this paper, we focus on smoke in case of fire and propose a realistic visualization method of volume data sets of smoke obtained from experiments or simulations. The proposed method realizes simultaneous visualization of both density and velocity of smoke by adding details to volume data based on systematic fluctuation reflecting time evolution of a velocity field. An implementation on a GPU realizes real-time visualization of dynamics of smoke.
