[Display omitted] •3D effect of the virtual EAST has been improved and data visualization has been realized in the ASEAST system.•Interaction behavior is created that the users can get information from database.•The system integrates data acquisition, data visualization and model visualization.•QT libraries are adopted to realize the cross-platform and impressive graphical interface.•In order to manage the models, the web-based model manager system is constructed. The Experimental Advanced Superconducting Tokamak (EAST) Device began operation in 2006. EAST visualization work has been paid more and more attention for simulating its running state and inner structure. The VEAST system had been developed to display the 3D model of EAST facility and some diagnostic data based on Java3D. Compared with the VEAST system, a new system named autosterescopic scientific EAST (ASEAST) using C/S (Client/Server) structure in combination with the technology of OpenGL and an open-source software system for 3D computer graphics and visualization called VTK (Visualization Toolkit) and the Qt5 libraries for the graphical user interface (GUI) has been developed to improve the 3D effect of the virtual EAST and visualize the experimental data. The ASEAST can be used to get access to the information of EAST and physical properties. In addition, as a general system, ASEAST supports a wide variety of 3D formats. The visualization result can be output in the corresponding format of the input. In order to improve the rendering speed, we used the classic QEM algorithm to simplify the models in preprocess stage. As for the 3D effect, we made an investigation and the survey revealed that the system had good 3D effect.
