|

// Definition of a face that bounds a polycone or polyhedra when it has a phi
|
|
// opening.
|
|
//
|
|
// Specifically: a face that lies on a plane that passes through
|
|
// the z axis. It has boundaries that are straight lines of arbitrary length
|
|
// and direction, but with corners aways on the same side of the z axis.
