FIG. 5.87
Create a cut on the foot's sole so we can remove the triangle at the heel.
Looking beneath the foot (Figure 5.87a), we can clearly see the large n-gon
at the front of the foot, but we also have a triangle at the heel. We will
remove the triangle i rst, and as we do so, we can help to reduce the n-gon
slightly.
●
Select the four main edges across the sole of the foot, shown in
Figure 5.87a .
●
Press
Alt
X
to cut them, creating a new line of edges (Figure 5.87b).
Although this has turned the triangle at the heel into a quad, the topology
isn't how we want it to be. Having this quad could lead to problems later
because it interrupts the natural l ow of the geometry, and has given us a few
poles. What we can do is simply remove it by merging the two central vertices.
●
To do this, select both central vertices and press
Ctrl
M
to merge them,
collapsing the polygon and cleaning up the heel as in Figure 5.87c.
Now let's tackle the larger n-gon.
At present, there aren't enough vertices around the n-gon for us to work with.
If we tried to connect these now, we would end up with some bad topology,
so subdividing the model further would lead to pinching.
We need to do some preparation work i rst. What we will do is create a cut
around the foot, ending at the n-gon. This will give us an extra vertex to use.
●
As shown in Figure 5.88a and 5.88b, select the ring of edges starting on
top of the foot, working your way underneath. When you reach the central
edge under the foot, turn the selection toward the n-gon.
●
If you now create a cut (
Ctrl
X)
, it will follow your selection, bending to
point toward the n-gon (Figure 5.88c).
