Acquiring Accurate Quality Digital Entities For Digital Twins within Virtual Reality

Creating digital entities (3D models) of digital twins for smart installations requires a number of considerations, especially when developing these to run on standalone virtual reality (VR) platforms. This paper provides an overview of the methods used for creating these digital entities for use with the Virtual Immersive, Remote Sensing, and Actuation (VIRSA) system. It explores conventional and cutting-edge techniques such as 3D scanning, laser-based surveys, photogrammetry, and procedural modeling. Additionally, the paper includes a thorough cost comparison between outsourcing and in-house model creation, considering factors such as initial investment, ongoing expenses, quality control, and scalability. Future possibilities in digital entity creation are discussed, envisioning advancements in this area. By equipping stakeholders with this knowledge, the research aims to optimize digital twin development, fostering innovation and enhancing the effectiveness of smart installations in various industries and applications.
