3d-tiles

As an OGC-approved open specification, it ensures long-term accessibility and utility across diverse tools and platforms, reducing vendor lock-in.

Supports combining multiple 3D geospatial content types like photogrammetry, BIM/CAD, and point clouds into a single dataset, as demonstrated in the README's image of CAD fused with photogrammetry.

Defines a spatial hierarchy for fast streaming and precision rendering, enabling efficient visualization of massive datasets at any scale from global to building interiors.

Preserves per-feature metadata to allow runtime interaction such as selecting, querying, and styling, which is crucial for analytical applications and highlighted in the specification.

Built on the glTF standard and directly supports glTF assets as tile contents, enhancing performance and compatibility with existing 3D graphics ecosystems, as noted in version 1.1 updates.
