3DF Zephyr vs MicMac

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.

MicMac is free, open-source desktop software for reconstructing 3D models from imagery. Developed at IGN and ENSG within the LASTIG lab, it runs on Linux, macOS and Windows under the CECILL-B license. It supports frame cameras, pushbroom sensors and scanned analogue images, along with camera calibration models and dense image matching for deformation studies. Outputs can include point clouds, 3D models and ortho-imagery in a desired coordinate system. Intermediate results in open formats let users work at different stages, and quality indicators include bundle adjustment residuals, covariance matrices, parameter sensitivity and correlation images. The C3DC command computes a point cloud from oriented images; AperiCloud creates a sparse cloud with camera positions and orientations for viewing in MeshLab, but does not support 64-bit PLY. MicMac is adapted to big datasets and was initially built for experts and researchers, with use also described in architecture, archaeology and forestry. Documentation, tutorials, a wiki and user forum are available. Building from source involves multiple dependencies, and the Mac guide cautions that a current revision may not compile or may be unstable on a given OS.
