Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Virtual Modeling of Analytical Monitoring of Chemical Reagents and Highly Pure Substances in Blender and Unreal Engine Software Applications A.M. BESSARABOV, D.A. GRISHAEVA, D.A. MOSKALENKO, V.E. TROKHIN Virtual models of analytical laboratories for chromatographic and instrumental analysis have been created for the leading developer of chemical reagents and highly pure substances, the Research Center "Fine Chemicals". The 3D model of the chromatographic analysis laboratory, implemented in the Blender application, has been imported into Unreal Engine 4. The necessary widgets for interactive user interaction with the model elements have been developed. In the virtual model of the instrumental analysis laboratory, created on the basis of the Blender application, all elements are considered in four categories: devices, equipment, electronics and furniture. In the "Devices" category, virtual models of the elemental CHNSanalyzer "Vario EL-Cube", the synchronous thermal analyzer "STA 449 F5 Jupiter" and the TVZ-2-PHP fl ash point determination device have been created. To improve the quality of interactive visualization, the virtual model has been imported into Unreal Engine 5. Keywords: virtual modeling, digital twin, Blender, Unreal Engine, chemical reagents, highly pure substances, analytical laboratory, devices, specialized equipment.
