This chapter introduces virtual reality (VR) modeling concepts. VR applications are successfully applied as a learning tool in different fields. After presenting a historic perspective of VR applications, the benefits of VR modeling, computing requirements, as well as their limitations are provided in this chapter. Essential VR development tools such as Unity 3D and unreal engine are discussed with 3D modeling. These platforms provide multiple sets of tools and minimize coding. They facilitate the user with enhanced capabilities such as rendering effects and interactive features. The steps followed in VR application development are presented subsequently.
