Study of 3D visualization of FAST Active Reflector based on OpenGL and EPICS

Active Reflector is one of the innovations of Five-hundred-meter Aperture Spherical Telescope (FAST), whose performance influences the performance of the whole telescope. To avoid the information acquiring being the bottleneck of the whole process and improve the efficiency of telescope observing, 3DViewer, a program of real-time 3D visualization for Active Reflector System (ARS) of FAST based on EPICS (Experimental Physics and Industrial Control System) and virtual 3D graphics technology- OpenGL, has been developed to display the status in ARS.
