Entwine vs PolyWorks|Inspector

Entwine is a Linux data organization library for building indexes of massive point-cloud datasets, from desktop-scale collections to trillions of points. Its build command creates an Entwine Point Tile (EPT) dataset, a flexible octree-based format. The project describes builds as lossless, retaining points, metadata, and precision, including at terabyte scale. Entwine can index any point-cloud format readable by PDAL, with documented storage types including laszip, zstandard, and binary. Input and output can use local storage or remote sources supported through Arbiter, including S3, GCS, and Dropbox. Commands accept options on the command line or settings in JSON files. The info command gathers file metadata before a build; merge combines completed subset builds, not unrelated EPT datasets. Output is shown with Potree, Plasio, and Cesium, and EPT can be converted to 3D Tiles for Cesium. An option enables AWS server-side encryption for S3 writes. Entwine is open source under the LGPL License; Conda is recommended as the fastest installation route, with source releases also listed.
