 vertices
 return the vertices of a polyhedron Calling Sequence vertices(obj) Parameters

 obj - polyhedron Description

 • The routine vertices returns a list of coordinates of vertices of the given polyhedron. It also returns the vertices of the vertex figure of a given polyhedron.
 • The command with(geom3d,vertices) allows the use of the abbreviated form of this command. Examples

 > $\mathrm{with}\left(\mathrm{geom3d}\right):$

Define a tetrahedron with center (1,2,3), radius of the circumsphere 4

 > $\mathrm{tetrahedron}\left(t,\mathrm{point}\left(o,1,2,3\right),4\right)$
 ${t}$ (1)
 > $\mathrm{vertices}\left(t\right)$
