: 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
The digitization of Chinese infrastructure extends into the media sector, where market research has historically tracked the explosive growth of digital services. : Moving beyond static 3D, new technologies from
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. Urban planning and digital twins in China have
: Visualizing this data within China often faces unique challenges due to mandatory coordinate shifting for maps, which can cause discrepancies between satellite imagery and map overlays.

This paper explores various facets of digital city modeling and media technology in China, specifically focusing on high-scale 3D urban representations and historical market shifts in digital television. Digital Urban Representation: 3D and 4D Modeling
: 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.
