Examples of pipes that have been produced using various x, y design parameters. The dark purple line depicts the growth curve of the pore nucleation points when the pipe is generated using the specified x and y design parameters; the dark purple points are the nucleation points, the lavender points are the vertices of each pore particle determined by the aforementioned equation, the lavender surface is the pore cross-section enclosed by the resulting vertices, and the nearly transparent lavender surface is the pore wall. (a) \(\varpi_{{\text{x}}} = 0,\varpi_{y} = 0\); (b) \(\varpi_{x} = 1,\varpi_{y} = 1\); (c) \(\varpi_{x} = 2,\varpi_{y} = 2\).
