What Entwine is

Entwine is an open-source data organization library for indexing large point clouds, from desktop-scale datasets to collections with trillions of points. Its build command creates an Entwine Point Tile (EPT) dataset, an octree-based format for point cloud data. The project describes its builds as lossless, preserving points, metadata, and precision, including at terabyte scale. Entwine can index any point cloud format readable by PDAL, including LAS/LAZ. Input and output paths can use local storage or remote sources supported by Arbiter, such as S3, GCS, and Dropbox. Commands accept settings through command-line options or JSON configuration files. The documented info command gathers file metadata before a build, while merge combines completed subset builds; it is not for unrelated EPT datasets. Entwine output is shown with Potree, Plasio, and Cesium clients, and EPT data can be converted to 3D Tiles for Cesium. An option enables AWS server-side encryption for S3 writes. Entwine runs on Linux and is available under the LGPL License. The download page recommends Conda as the fastest way to get started, and lists source releases.

Good

  • Lossless builds preserve points, metadata, and precision
  • Indexes formats readable by PDAL
  • Supports local storage and several remote sources
  • EPT output works with listed visualization clients
  • Includes an AWS server-side encryption option for S3 writes

Watch out

  • Merge is limited to completed subset builds
  • Runs on Linux

Who it suits

Entwine is suited to teams organizing point cloud datasets, including large collections, and working with PDAL-readable formats or local and supported remote storage. Its documented tools and integrations may also suit workflows using Potree, Plasio, or Cesium.

Verdict

Entwine provides point cloud indexing, storage options, and EPT output for several listed clients. Its merge command is specifically for subset builds, not unrelated EPT datasets.
