Description
Tokamak is a complex nuclear fusion reaction device composed of numerous systems. During physical experiments, different systems will obtain massive amounts of experimental data, which are highly specialized and require domain knowledge and specific tools to view and analyze. In addition, tokamak devices, as important nuclear fusion reaction devices, have strict management mechanisms and are not easily accessible. We develope a fusion device experimental data visualization system, based on the EAST device and using EAST tokamak experimental data, to construct a visualization system framework and basic platform. Three kinds of data visualization are integrated into the virtual platform: magnetic topology data, electromagnetic measurement data, and real time plasma shape data. In the processing of plasma physics experiments, real-time visualization of these data can help researchers capture key information in a timely manner and assist in scientific decision-making. Directly displaying intangible physical parameters in a proportional virtual device helps physicists understand fusion systems and also determines the operating status of the device through various diagnostic data. 3dsMax is used for modeling and processing, Maya is for model animation production, Unreal Engine 5 engine is for rendering, particle effects production, packaging, and publishing into cloud rendering mode through WebRTC protocol, achieving lightweight access to B/S architecture. The system has implemented the entire process of data collection, data cleaning, data storage and data transmission. In the future, more diagnostic data will be visualized in this system, and more efficient ways of data processing will be summarized using this system.
