3DF Zephyr vs Postshot

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.

Postshot is a Windows application from Jawset for reconstructing photorealistic 3D scenes and objects from photos or video with radiance field technology. Its workflow covers tracking, training, editing, and rendering, with image masking, region-of-interest training, scene merging, and model sequence rendering. Inputs include JPG, PNG, TIF, EXR, DNG, and RAW images plus MOV, MP4, and MKV video. Exports are PLY, SPZ, and HTML, and integrations include Unreal Engine and After Effects. Free supports COLMAP and RealityScan camera and point imports. The Free plan allows unlimited image count, video length, and model size, with output up to 4K SDR (8-bit) for non-commercial use. Indie adds watermark-free renders, commercial use, floating licensing, and PLY/SPZ export. Studio adds further formats, above-4K and HDR output, command-line use, and AprilTag alignment. Free costs nothing; Indie and Studio are also listed at free.
