A Rust library and CLI tool for processing 3D Tiles data.

Early stage of development. Developed at the TUM Chair of Geoinformatics. Contributions welcome.

Features:

• Converts point clouds to 3D Tiles 1.1 using octree spatial indexing
• Supports LAS, LAZ, E57, XYZ, and XYZ+Zstandard input formats
• Reprojects from any EPSG coordinate system to ECEF (EPSG:4978) using PROJ
• Encodes RGB colors from input point clouds into GLB tiles
• Outputs implicit tiling subtrees for efficient streaming

A command-line tool for converting point clouds to 3D Tiles.

Download pre-built executables for your platform from the release page.

On macOS, you need to remove the quarantine attribute after downloading:

xattr -d com.apple.quarantine ./etiles-cli

Docker:

docker pull ghcr.io/tum-gis/etiles-cli

From source:

cargo install [email protected] # replace with the latest version

etiles-cli convert-point-cloud \
  --input-path /path/to/pointcloud.las \
  --output-path /path/to/output.tar \
  --source-crs 25832

For a full list of options:

etiles-cli convert-point-cloud --help

Convert an entire directory of point cloud files:

etiles-cli convert-point-cloud \
  --input-path /path/to/point_clouds/ \
  --output-path /path/to/output.tar \
  --source-crs 25832

Docker:

docker run --rm \
  -v /path/to/data:/data \
  ghcr.io/tum-gis/etiles-cli \
  convert-point-cloud \
  --input-path /data/pointcloud.las \
  --output-path /data/output.tar \
  --source-crs 25832

Both the CLI and library produce a TAR archive containing:

• tileset.json — root 3D Tiles 1.1 document with implicit tiling metadata
• content/content_{level}_{x}_{y}_{z}.glb — binary glTF tiles with point positions and colors
• subtrees/{level}.{x}.{y}.{z}.subtree — implicit tiling subtree availability metadata

The single-file archive simplifies transfer and can be extracted on the target machine.

A Rust library for integrating 3D Tiles generation into your own application.
