Visualization of Dust Particle Data with Plasma Simulation Results Using Virtual‐Reality System

Abstract

We develop the environment in which the time-sequence experimental data of three-dimensional dust particle positions observed by the stereoscopic fast framing cameras is visualized in one virtual-reality space with the results of the equilibrium plasma simulation in the vessel device data integrally using a virtual-reality system. Since their three-dimensional relative positions can be displayed, it is possible to analyze the three-dimensional relationship between the dust trajectories, the magnetic-field structure, and the devices in the vessel. It is confirmed that the observed dust particles are distributed in the periphery region. Most dusts move along the magnetic-field line, but some particles move radially across the lines with sharply curved trajectories. The transport direction varies from place to place. This system promoted the viewers' understanding.

“…Since we do not have enough time before the experiment starts, we utilize the existing CAVE system and modify our developed software previously. The software includes an interface for reading the threedimensional coordinate data of particles and a rendering function of particles by the pointsprite method [35] for visualizing the loss points as spheres. This software is written in C++ with OpenGL and CAVELib library.…”
