Geometric Portraits




I believe that not all facial expressions are universal. According to an article by greatergood.berkeley.edu, most facial expressions are universal. However, there are some that don't quite meet this theme. Popsci.com says that some tribes use expressions differently. They gave different tribes pictures of expressions to identify. The results prove that the preceding statement about different cultures having different expressions to be true. Despite that, most expressions are universal no matter what the tribe may be.


In GT, we are doing a low-poly-portrait. It is a very complicated process indeed. First, you put a portrait into photoshop. Second, You outline the subject and draw triangles over the subject's features (smaller triangles = more detail) with photoshop's line tool. Third, you merge all those shapes to create one layer and put it on top of your portrait layer and put a position lock on it. Fourth, you make a WHITE background layer and leave it on the bottom. Then, you use the polygonal lasso to outline each and every triangle (one at a time) and colorize them. After going through all those steps, you should end up with a finished low-poly-portrait.



I made 3 low poly portraits so far. The first one shouldn't even count, for it was so easy. I just uploaded an image to a website ant it triangulated everything. the only downside is that EVERYTHING was RANDOMLY triangulated and barely anything was legible, let alone my face. The second one (the first one made in photoshop) was much better. The final product was much more precise. Unfortunately, the original photo was taken with a low resolution camera (the computer's webcam to be exact). It was also really bland because I just averaged the colors. The most current one was the best one by far. We got to skip the outlining process which saved a lot of time that would later be used in refining the details of the image. The background was also a unique low poly image in it's own way.

This is the ULTIMATE low-poly that was not talked about in the post. This one has a broken glass effect.
