In the 5th paragraph of the sub clause ‘3.2 Element complexity’, the correct explanation for Fig. 4 is presented below.
“Figure 4 shows a comparison of the CEi of two hexahedral features. F0 consists of six planes and 12 straight lines, and F1 consists of four planes, two cylindrical surfaces, eight straight lines, and four arcs. Therefore, F0 has a smaller CEi than F1. Suppose these features have the same volume. Then, the FSC of the features will be FSC0 = (1/0.857)(1 + 0.857) = 2.167 and FSC1 = (1/1)(1 + 1) = 2 (i.e., FSC0 > FSC1). Hence, F1 will be removed first, because a feature with a higher CEi affects the data size of the original model to a greater extent. The introduction of FSC is closely related to the main purpose of research on simplification, where the aim is to preserve the outer shape of the original model and minimize the data size simultaneously.”
