What is a 3DT file?

3DT files mostly belong to 3D Mapper. 3DT files are specialized files that store 3D Tiles data inside a ZIP-based container.
They encapsulate a complete 3D model along with its geometry, textures, and metadata, optimized for streaming and display in mapping applications.

The file’s internal structure relies on ZIP compression.

It is mainly used in geospatial contexts for 3D mapping and visualization.

Both 3D Mapper and ContextCapture Center produce these files.
