SuperMap HiFi 3D SDK for Unreal(Basic) offers users access to real world geospatial 3D data from the SuperMap Platform or other open online maps. SuperMap’s 3D GIS technology and various geospatial data streaming (including global-scale imagery and terrain, TB-level of oblique photogrammetric models, point clouds, man-made models, BIM of real-world coordinates) as S3M, could enable game engines to stream geospatial data in a more accurate, interactive way. At the same time, it combines the basic capabilities of the game engine effects to provide a immersive and practical experience.
