I´ve got that image from another EA game.
Then by having some fun I looked for the similarities with the FIFA faces and then by taking my own conclusions and testing, I found out that what appears on that image I made, can be applyed to the FIFA faces.
The only diference is that on FIFA, they only use half of the face, wich make´s the game to loose some details and become more compatly with all systems, but also allows less problems for players with bad computers, but some disavantages to players with good computers as they cannot have full perfection.
The best way to explain the graphic is, the the bigger image on the top, only the white lines only is the face or head in wireframe format(meaning: something like having the bones of the player face, the facial structure lyes beneath the face textures or beneth the skin).
Then the 2 images below show the comparision beetwen the real face on the left and the face changes(streching, resizing, scaling) to fit correctly above the wireframe structure.
With this image I made, it will benefit the face makers as a small guide for better orientation when converting the real players faces.
I hope this fits everyone, post some comments on agreement or disagreement and if this fits for something or not.
