The supported model formats include: {{(idx > 0 ? ", " : "") + format}}
. b3DM files typically contain geospatial data such as buildings, terrain, vegetation, etc. These data exist in the form of 3D models and can be visualized and analyzed on virtual Earth platforms or other 3D geographic information systems.
The. b3DM file stores data in binary format, which makes it more efficient and can accommodate a large amount of geometric information, texture maps, and other attribute data.
. b3DM files typically use compression algorithms to reduce file size and improve transmission efficiency. Common compression algorithms include glTF Draco compression based on Magic Number and quantization compression.
The. b3DM format is widely used in fields such as virtual earth platforms, GIS software, and game development. For example, the 3D Tileset format in CesiumJS is based on. b3mm files, used to present large-scale geospatial data in web browsers.
