Finally, I restored my old applet (from 2015).

__a Construction the coordinates for Convex Polyhedra__The peculiarity of this applet is that for a given number of**n**particles on the sphere, their extreme distribution is found. The maximum of the**sum of distances**is found directly: maximization using the Maximize[]command and sliders as in https://www.geogebra.org/material/show/id/dVXk2Gbq.__b Triangulation of polyhedral surfaces__This section sorts and finds vertices, faces, and surface segments of a polyhedron and its dual image.__c Visualization of polyhedral surfaces__In this section, the elements of the polyhedron and its dual image are directly translated into their**3d****form**.
