Chapter 7 is about 3D scenes and how this is accomplished via extended reality systems such as VR, AR, and MR. Maps that use 3D scenes can be realistic or cartographic. 3D scenes have a few main elements including surfaces, features, textures, and atmospheric effects. 3D scenes can also have textured or untextured layers to visualize complex digital models which typically has an overview, discipline, category layer, filter, integrated mesh scene layer, point cloud scene layers, point scene layers, and volex scene layers. This technology can be used for many things such as building metaverses and urban planning.
