The digitization of Chinese infrastructure extends into the media sector, where market research has historically tracked the explosive growth of digital services.
: Large-scale urban models for Shenzhen and Shanghai often exceed 5 million polygons. These models are typically provided in formats such as Cinema 4D, OBJ, and FBX, and include detailed layers for buildings, roads, and land use.
: Moving beyond static 3D, new technologies from Chinese startups like 4DV.ai allow for the reconstruction of 2D video into navigable 4D scenes. This "4D splatting" integrates spatial and temporal cues, allowing users to rotate viewpoints and move through a scene during playback in real time. Data Graphics and Media Landscape
Urban planning and digital twins in China have increasingly relied on massive-scale 3D models developed using GIS data and AI photogrammetry. These models, often spanning over 100km, serve as foundational assets for smart city visualization, real estate marketing, and simulation environments.
