VisualSFM is a lightweight, specialized, third-party software solution that was developed to help advanced computer users such as programmers or software developers perform 3D reconstructions by making use of "structure from motion" or SFM.

To get more technical, this application is actually a utility that "exploits multi-core parallelism in feature detection, bundle adjustment, and feature matching in order to run very fast."

The 3D reconstruction process can be as easy as pressing a bunch of buttons in the program's main window. First, a few images must be added by clicking the designated buttons in the toolbar, then match them by clicking the four-arrow button in the same toolbar.

The next two steps consist of the "sparse reconstruction" process and the "dense reconstruction one," each of which available, you guessed, on the same toolbar, as buttons.

If you're a more seasoned user who isn't buying this whole GUI (Graphic User Interface) nonsense, you could perform the whole process from the Command Line without a GUI. All you have to do is run the "VisualSFM sfm+pmvs ./images ./result.nvm" code and you're set (assuming you know what you're doing).
