In virtual reality (VR), a visual model of an item of equipment item is usually produced using 2D and 3D models or laser scanned point cloud data with images. Modelling the equpment’s functionality, creating a digital twin (DT), is a demanding task if the model is expected to accurately represent all system features. The complexity of modelling can be an obstacle for small and medium-sized enterprises, discouraging the utilization of digital twins.
