154 CHAPTER 5 Using VisUalization techniqUes

In Figure 5.9, the Zebra Stripes in example A do not match across the edge labeled A at all.
This is clearly the nontangent, contact-only case. Example B shows that the stripes match in
position going across the indicated edge, but they change direction immediately. This is the
tangent case. Example C shows the stripes flowing smoothly across the edge. This is the curva-
ture continuous case.
You can use the remaining icons in the View toolbar to toggle the display of various types of
entities from reference geometry to sketches.
Curvature colors the model with various colors depending on the local surface curvature.
Mathematically, curvature is the inverse of radius, so c = 1/r. A large radius is a small curvature
and vice versa. Generally, on models where you are looking at curvature, you are looking for
sudden changes, flat spots, constant radius, or inflections. Figure 5.10 shows a model of a cricket
bat with the curvature displayed.

View Orientation
The View Orientation dialog box and the Standard Views toolbar are very similar to one another.
View Orientation is the more modern of the interfaces. The View Orientation dialog box and
the View Selector are shown in Figure 5.11.
