VR을 이용한 해양과 기상 자료의 과학적 가시화

Abstract

Scientific visualization of time-varying oceanographic and meteorological data using VR technique provides scientists an immersive and interactive environment to explore and analyze the complex processes. The advantage of using the VR technique in multidimensional scientific data has been demonstrated. A new VR display system named as VOSS (Virtual Ocean Simulation System) has been configured for development of VR application ot ocean environmental exploration. The VOSS is a big screen VR environment system consisting of motorized reconfigurable, rigid 4 walls (each 3.2m x 2.4m) that can change into types of I-wall, CAVE, sandwich and any desired angle of the wing screens. We will present the 5-D representation of oceanographic processes in VR images on the VOSS system. The purpose of this paper is two-fold. We will examine firstly the VR usage in exploring the oceanic processes. and secondly the differential advantage of various shapes of VR display screens. We demonstrate two cases of oceanographic processes; One shows the developing stage of the typhoon Maemi that hit the southern coastal area of Korea in September 2003. The other is for the dilution of Changjiang river discharge into the Yellow Sea. The present studygive a good promise to improve our understanding the internal processes by intuition obtained through using the VR advantage.
