3D Face Model – How to Make a 3D Model of Your Face

At this point, it’s important to note that, for the options discussed so far, there are two types of techniques used to produce 3D models from real-world objects: photogrammetry and 3D scanning.


Photogrammetry consists of taking multiple pictures at different angles and later stitching them together. This is what’s typically done using a smartphone, webcam, or camera.

The advantages of this technique are that it requires less sophisticated equipment, doesn’t require a PC to be used simultaneously, and can be done in outdoor environments. The main drawback is that the final results aren’t generally as clean as with 3D scanning.

Moreover, photogrammetry requires a lot of processing power in order to turn photos into a 3D model. With a slow computer, this could mean a tiring process.

3D Scanning

Although the 3D scanning process might appear similar to taking pictures, what’s happening in the “background” is much different. That’s because the scanner, with the help of a PC, generates the model as it identifies points on the surface of the target object.

Some scanners can provide outstanding scan quality, and scans are done in real time without the need for heavy post-scan processing. Nevertheless, the scanning device itself typically represents an extra expense and cannot easily be used outdoors.
