|
|
// The polygonal solid G4BREPSolidPolyhedra is a shape defined by an inner
|
|
// and outer polygonal surface and two planes perpendicular to the Z axis.
|
|
// Each polygonal surface is created by linking a series of polygons created
|
|
// at different planes perpendicular to the Z-axis. All these polygons all
|
|
// have the same number of sides (sides) and are defined at the same Z planes
|
|
// for both inner and outer polygonal surfaces.
