Reality models provide real-world context using aerial imagery and/or photographs. Technologies like 3D imaging and photogrammetry with the use of UAVs (unmanned aerial vehicle) provide these images to be used in software for converting a 2D map to a 3D model. Examples of software for this approach are ContextCapture by Bentley and VUE, PlantFactory, Ozon, Drone2Map by ESRI, or CarbonScatter by E-on.

LumenRT, for example, is an E-on software licensed by Bentley. It can create real-time immersive experiences. It presents a combination of tools that create ultra-high-definition videos and photographic images for 3D projects.

One of the methods for creating 3D structures from 2D images is structure from motion (SFM) photogrammetry. There are several software packages for creating and reconstructing three-dimensional structures: Agisoft, VisualSFM, CMPMVS, Meshlab, and Blender. For instance, Aibotix GmbH has created a 3D model of Castle Spangenberg in Germany using a combined mapping workflow. Data was collected with multirotor UAV Aibot X6 and ground surveying equipment. The collected data was then processed with the help of Agisoft PhotoScan.
