Digital-LHD: LHD Visualizer for Head-Mounted Display Systems

Abstract

We developed a virtual reality visualization program, Digital-LHD, for modern Head-Mounted Display (HMD) systems. Digital-LHD provides an immersive environment for the interactive visualization of plasma data related to the Large Helical Device (LHD). Its predecessor, Virtual-LHD, was developed for CAVE systems, which were limited in accessibility due to their cost and size. The newly developed Digital-LHD utilizes Unity and C# to offer interactive 3D visualization. Digital-LHD includes features such as isosurface rendering, magnetic field line tracing, particle trajectory visualization, and new functionalities like local arrow glyphs and a plasma pressure color contour. The enhanced interactivity and intuitive GUI have improved the user experience. Digital-LHD enables fusion plasma researchers to perform immersive visualizations with HMDs, providing a more accessible and cost-effective solution.
