#### 10.9.8 Cylindre

• Cylindre( <3Dpoint>, <3Dvector>, <radius> [, nb faces, hollow] )
• Description: that macro returns a polyhedron representing the cylinder built from a <3Dpoint> that is the center of one of the two circular faces, a <3Dvector> of the axis showing the orientation and the height of the cylinder, a <radius> and the number :<nb faces>, that last is $35$ by default. The parameter <hollow> is $0$ or $1$ ($1$ by default) shows if the cylinder is hollow or not, if not, the two circular faces are added to the facet list, those are the two first in that list.
