Finishing the Skull Shape
The face is looking great, but you still need to create a full head. This section will cover
how to do that by extruding from the forehead.
1. Go back up to the forehead geometry. Extrude the top edge loops upward once, and
then align them along the z-axis. It is much easier to create head geometry with even
loops. Rotate the aligned edges to create a good basis for extruding the next part of
the skull curve (Figure 3.48).

2. Continue to extrude the head shape until you have gone around the skull to the back
of the neck. When you have reached that point, similarly extrude from the bottom of
the chin to create the area around the throat. Fill in the void between the front and
back of the head by extruding edges and creating new faces by creating quads out of
sets of four vertices with the F key. When you are finished, you should have some-
thing that resembles Figure 3.49.
3. When looking at your newly-modeled head, you will see that it has very flat sides in
its current form. Move edge loops outward with the Proportional Editing tool acti-
vated to create a better head shape. Use Figure 3.49 as a guide.

For developers creating head geometry for iOS and Android games, some of the techniques
here may produce polygon counts too high for characters. Curves like those surrounding the
head shape and facial features are great places to be frugal with polygons. Try to create the
shapes of these facial curves with as few polygons as possible.
