Abstract

We have developed a glassless stereoscopic visualization system for the real-time numerical simulator of the interplanetary space–magnetosphere– ionosphere coupling system, adopting the three-dimensional (3D) magnetohydrodynamical (MHD) simulation code. Our real-time Earth's magnetosphere simulator numerically reproduces the global response of the magnetosphere and the ionosphere at the same time with the real world by using the real-time Solar wind data, and has shown two-dimensional (2D) figures of the global magnetosphere of about 1 hour in advance in virtual reality at every minute on Web since November 2003. We implemented 3D graphical techniques such as volume and iso-surface rendering for visualizing scalar variables and also colored 3D streamlines for representing the magnetic field for standard and glassless stereo-displays. A real-time interpolation method mapping the simulated data to structured uniform rectilinear grids commonly utilized in computer graphics was developed, so that this 3D visualization system is capable of monitoring the real-time Earth's magnetosphere simulated data in on-line mode.
