#### 10.9.3 Cone

• Cone( <3Dpoint>, <3Dvector>, <radius> [, nb faces, hollow] )
• Description: that macro returns a polyhedron representing the cone built from a <3Dpoint> that is the tip, a <3Dvector> showing the orientation axis and the cone height, a <radius> of the circular face and the <nb faces> number, that number is $35$ by default. The <hollow> parameter is $0$ or $1$ ($1$ by default) shows if the cone has to be hollow or not, if not the circular face is added to the facets, this is the first in the list.
