**3. Practical examples using CASP methodology**

#### **3.1. Curvature graphs**

As we have already explained, the curvature graphs were not used directly, but were used just to show how they work. We will present some examples. Curvature graphs were used to determine non-symmetry on a real face scan as **Figure 5** shows. The highest peak on the curvature graph represents the nose, which is in the middle. The left and the right sides of the curvature graph will be symmetrically identical over this peak on a perfect symmetrical face, but it is not in this case. That way, we proof non-symmetry that is not obviously seen on a real face scan.

**Figure 6** shows a series of increasing accelerated curves (a) with their curvature graphs (b) and a series of increasing decelerated curves (c) with their curvature graphs (d).

The last example of curvature graph use is the ergonomic fit of a thumb on the computer mouse as shown in **Figures 7** and **8**.
