Like father, like son. Comparing siblings in 3D

Comparing siblings in 3D just got easier with peel 3d scanners. It was a fun project one ingenious father took on.

As a parent, one of the most common things you are likely to hear is: “Oh my, he (or she) looks just like you!”. And that is no mystery; our children are an extension of us; they bear the same genes; the resemblance is therefore not a coincidence at all. But, besides the visual similarities, did you ever wonder how closely related you are with siblings? We tried to answer this question with this little experiment we did.


Our subjects (we will call them son 1 and son 2) are 26 and 30 respectively; they share the same parents. Using a peel 2 scanner, we started by scanning their faces. The process was pretty straightforward. All that had to be done was point and shoot. The scan was completed within seconds.

Right off the bat, it is pretty obvious that the two are related as they bear a resemblance. To take our experiment further, we aligned the two faces in peel 3d software using best fit alignment. This method tends to minimize the distance at any point between the two scans and gets them as close as possible to each other. We can then proceed to a colormap between the two subjects:



The comparison showed that son 1 has a more prominent eyebrow and

slightly elongated nose while having a somewhat narrower face. The rest of their faces are actually quite similar (within 2mm).

Of course, this project was done for fun, but the results are quite interesting as they now allow us to quantify the resemblance very accurately between two individuals. If you want to hear more about this experiment, you can view a video we made here. We took things a little further, adding the girlfriends in the mix! Enjoy!
