Polyhedron - graphics objects:
The field polyhedron.vertices is a matrix in which each row presents (x,y,z) points. The field polyhedron.faces defines the faces: for illustration the first row in the matrix identifies to draw a line from vertex 1 to vertex 2 to vertex 3 to form the first face. The face color to set is grey and the edge color to black. The figure, which is as shown in figure, displays only two faces. By using the rotate icon on the Figure Window, the figure can be rotated to see another edge as shown in figure:
