3D mapping is a technology that creates three-dimensional representations of physical spaces or objects. It uses various techniques, such as laser scanning and photogrammetry, to capture detailed information about the shape and features of an area. This data is then processed to produce a digital model that can be viewed and analyzed from different angles. This technology is widely used in fields like architecture, urban planning, and gaming. By providing a realistic view of environments, 3D mapping helps professionals visualize projects, plan developments, and enhance user experiences in virtual worlds.
