Logically, to get your webcam to generate a three-dimensional recording you have to record with more than one camera from different angles, or with the same webcam recording from different positions, since every webcam records flat, in only 2 dimensions. That is, getting 3D is a very complicated job that needs a lot of expertise, skill, a lot of time and patience.
This is the reason that there is a program like StereoPic, which will allow you to record with your webcam in stereo mode, focusing from two angles, so that, thus, the final result of the recorded video is totally three-dimensional.
StereoPic works with most existing webcams.
You can free download StereoPic and safe install the latest trial or new full version for Windows 10 (x32, 64 bit, 86) from the official site.
