Entwine vs Leica Cyclone 3DR

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.

Leica Cyclone 3DR is Windows desktop software for converting point cloud data into 3D models and deliverables. Its workflows cover inspection, modelling and meshing, with tools for cleaning data and automating processing through AI classification and scripting. Users can build 2D and 3D models, meshes and textures, inspect reality-capture data and generate reports. Scan2Verify creates prefilled QA/QC reports from scan data. PRO Edition packages add specialised tools for AEC, Survey and Plant industries.

The software works with Cyclone FIELD 360, Cyclone REGISTER 360 PLUS, Hexagon GeoCloud and downstream products such as CloudWorx. Listed formats include LGS/LGSx, E57, LAS/LAZ, IFC, RVT, FBX, DWG and DXF, though some depend on the license. The 2024.0 release notes specify 64-bit Windows 10 (Build 1809) or Windows 11. Leica recommends at least 16 GB RAM for regular desktop workflows, and 32 GB plus a supported NVIDIA GPU for auto-classification. A companion Free Viewer supports viewing and basic inspection tasks without using a full Cyclone 3DR license.
