positioning your vertices in a
diamond formation can allow
you to fill in spaces that would
otherwise hold triangles or
ngons (faces with more than
four vertices). Figure 3.51 shows
a potential solution.
4. Extrude some of the outer faces
of the new ear geometry, as
shown in Figure 3.52.
5. The ear smoothly comes off the
head, so you should delete the
faces at the front tips of the ear
extrusion. Also delete the faces
that were adjacent to the newly
deleted faces on the flat side of
the head. Create new polygons
between the edges on the ear extrusion and the flat side of the head. Clean up the
geometry further until you have a result similar to Figure 3.53. In the figure, notice
that one less edge loop is coming from the head—this is because a row of polys were
deleted while cleaning up the geometry.
