<p><span style="font-size:11pt"><span style="font-family:Calibri,sans-serif">The article discusses the fields of application and content of virtual reality systems, the results of a comparative analysis of virtual educational environment platforms, and their role in presenting educational content in a virtual electronic format. The subject of research is geometric modeling, visualization methods and software tools of 3D models of objects in virtual environments. The purpose of the research is to develop algorithms for the representation and visualization of 3D models of exterior and interior objects in the organization of a virtual university, as well as a software tool for creating 3D models in the organization of a virtual university. Scientific novelty of the research, we offer new methods for geometric modeling of 3D objects in visualization, i.e. constructive logic-algebraic R-function method (RFM). The practical results of the research are aimed at increasing the activity of learners in modern virtual 3D environments in educational institutions based on the software tool, and thereby supporting the teaching process in the virtual three-dimensional environment designed on the basis of modern national landscape design in the Uzbek language “vAcademia.uz” software was developed</span></span></p>
