 Calling Sequence IsStellated(ngon)

Parameters

 ngon - polyhedron

 • The command with(geom3d,IsStellated) allows the use of the abbreviated form of this command.

Examples

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

Define a stellated icosahedron

 > $\mathrm{stellate}\left(\mathrm{sico},\mathrm{icosahedron}\left(\mathrm{ico},\mathrm{point}\left(o,0,0,0\right),1\right),46\right)$
 ${\mathrm{sico}}$ (1)
 > $\mathrm{IsStellated}\left(\mathrm{sico}\right)$
 ${\mathrm{true}}$ (2)

Plotting:

 > $\mathrm{draw}\left(\mathrm{sico},\mathrm{style}=\mathrm{patch},\mathrm{lightmodel}=\mathrm{light4},\mathrm{shading}=\mathrm{XY},\mathrm{orientation}=\left[-142,-127\right],\mathrm{title}=\mathrm{stellated icosahedron - 46}\right)$
