3DF Zephyr is the complete photogrammetry software solution.


Since version 5.0, the old "3DF Zephyr Pro" and "3DF Zephyr Aerial" versions have been merged into one single version, called "3DF Zephyr". Please contact support@3dflow.net for any question you may have!


Our two additional flavors, "3DF Zephyr Lite" and "3DF Zephyr Free" remains the same.


3DF Zephyr is the complete photogrammetry software solution dedicated and designed for topography, urban monitoring, natural hazard, mining, UAV, precision agriculture applications, architecture, archaeology, medicine & dentistry, body scanning, vfx and much more.


3DF Zephyr Lite/3DF Zephyr Lite Steam Edition is a commercial solution aimed at small businesses, artists or in general to those users who just want to obtain a 3D mesh and/or those who don't need all the tools available in the complete edition.


3DF Zephyr Free is a completely free edition, excellent for sharing your project files with customers, friends and colleagues. Although it has serious computation limitations (for example,a maximum of 50 pictures can be used) it is still a great viewer and the perfect way to learn the ropes of photogrammetry.


3DF Zephyr and 3DF Zephyr Lite require online activation. 3DF Zephyr Lite Steam Edition must be run through the Steam application.


3DF Zephyr also comes in an education version, with the same functions and features but without a commercial licensing. 3DF Zephyr Education is dedicated to students, teachers and schools.
