3DF Zephyr Free
3DF Zephyr Free is a standalone photogrammetry software from 3Dflow and it is completetly free for personal use.
You can reconstruct 3D models using up to 50 pictures (or frames from a video), export textured meshes and import project files generated with other versions of Zephyr.
This photogrammetry software is excellent for beginners or to evaluate the purchase of 3DF Zephyr Lite, a low-cost (but less limited) version of Zephyr, since most of the - many - included tools are also available in both versions (point cloud cleaning, mesh filters, etc.)
This software is a direct competitor of the free version of Autodesk Remake - a great comparison by Youtuber iontrades of these two photogrammetry software is available on iontrade's channel.
Photogrammetry.software recommends this solution especially to beginners and as a 3D viewer.
