In their own words
3DF Zephyr
3DF Zephyr is Windows desktop software that reconstructs 3D models from photos, with workflows involving camera sensors, drones, and laser scanners. It estimates camera parameters automatically and offers global or incremental reconstruction pipelines. Outputs include orthophotos, orthomosaics, DEMs, contour lines, sections, CAD drawings, measurements, and project reports. Users can upload models to Sketchfab and videos to YouTube; Unity ArtEngine integration is described for people with an ArtEngine license. Plugins include native support for several laser scanner formats, a beta Canon DSLR remote-shooting plugin, and an experimental GEOBIM Revit plugin. Python scripts and XML files can automate workflows and batch processing. The free plan is for personal use and allows 50 photos or video frames, with limited exports and editing. Zephyr requires Windows 10 or 11, at least 16 GB of RAM, and 20 GB of free disk space. The listed Lite plan costs €199 a month, while the full Zephyr plan is listed at €4,200 a month.
KIRI Engine
KIRI Engine is a 3D scanning application that creates models and visualizations using photogrammetry, Neural Surface Reconstruction, and 3D Gaussian Splatting. Photo Scan creates 3D models from photos. LiDAR Scan supports model scans, floor plans, and quick scene visualizations on LiDAR-equipped iOS devices, while Featureless Object Scan is designed for shiny, reflective, transparent, and low-texture objects. The free Basic plan costs nothing and permits up to 150 photos and 2 GB per scan, with unlimited scans and free exports. Pro costs $17.99 a month or $79.99 a year, and raises the limits to 500 photos and 5 GB per scan while adding faster queue processing and advanced scanning and modeling features. The API offers Photo Scan, Featureless Scan, and 3DGS Scan; each API call uses one credit. Credits cost 1.00 USD each, with a 500-credit minimum recharge and 10 free test credits at sign-up. Other listed tools include a website model embedder, a UE5 plug-in, and STL export. Uploaded photos and videos are processed on cloud servers, and local PC scanning is not on the company's roadmap at the moment.
