3Dflow

3Dflow SRL is a software company in Verona, Italy. It builds photogrammetry and 3D reconstruction software that turns photos and laser scans into 3D models and maps.

Its main product is 3DF Zephyr. The company says it handles everything from photos to point clouds, meshes and Gaussian Splats, and on to elevation models, contour lines and drawing elements. It works with any camera, drone or laser scanner. Version 9.0 adds Gaussian Splat creation, satellite map tiles in the viewport, faster photoconsistency and unified selection tools. Versions include Zephyr Free and Zephyr Lite. Users can try the full program for 30 days, and later choose a subscription or a perpetual licence.

3DF Scarlet is a companion tool for laser scan and LiDAR registration. It joins large scans with coarse, fine, ICP or photogrammetry-based methods, and it is included in 3DF Zephyr at no extra cost. The company builds all its own algorithms, from camera orientation to texture generation, and uses multi-GPU support to speed up the work.

Developers can use FlowEngine, the engine that powers 3DF Zephyr, as a C++ software kit for Windows and GNU/Linux. It lets them build their own reconstruction apps, and a free version is available.

The software is used in many fields. In surveying and mapping, it processes aerial images from drones and UAVs into true orthophotos and elevation models. In mining, it calculates stockpile volumes and contour lines. In construction, it merges photo and LiDAR data. Other users work in architecture, cultural heritage, visual effects and gaming, 3D printing, agriculture with multispectral images, and engineering.

3Dflow also supports its users with tutorials, a manual, a forum, a Discord community and certified trainers. It runs an education programme, a reseller programme and a case study library.
