#### **Table 1.**

*The parametric values of a pyramid.*


**Table 2.** *Precise pyramid values.*

2.The walls are described by the edges (E1, E2,…).

3.Edges are represented by vertices (A, B, C,…).

4.Vertices are represented by three-dimensional coordinates (X1, Y1, Z1,…).

For the parametric setting of a regular quadrangular pyramid (**Table 1**), values for the coordinates of each vertex of the three-dimensional space must be set. The pyramid's height is set with parameter **h**, and the length of the base with parameter **a**. When vertex number five values for the X or Y coordinates is a non-zero number, the result will be a tilted pyramid. The first four vertices form the base of the pyramid, and the fifth is the top of the pyramid. The peaks are crawling in the same direction in the counterclockwise case, starting from the IV quadrant (**Table 2**).
