With Virtual Reality (VR) technology becoming increasingly advanced and affordable, it is expected to also increasingly permeate our everyday lives: from applications in the domain of training (e.g., flight and medical simulators), health care (e.g., anxiety treatment, rehabilitation), and education (e.g., visualizing molecular structures) to the Metaverse. VR and virtual environments (VEs) also offer new and exciting possibilities in the aid of psychological research, as they promise the high realism of field experiments while maintaining similar experimental control as the classical laboratory study. Whether one is interested in designing a VR application, in studying how VR affects and can be optimized for its users, or in using it as a tool for psychological research, modeling and rendering a 3D virtual scene is an important skill. In this introductory course, you will get acquainted with 3D modeling and VR rendering software (a real-time visualization tool) and develop the basic skills and knowledge that allow you design and built your own interactive desktop VE
