Public Member Functions

 Portal ()
 Constructor.
std::vector< fvec3 > & geometry ()
 The set of points defining the shape of the portal. The points must define a planar convex polygon and must be in world coordinates.
const std::vector< fvec3 > & geometry () const
 The set of points defining the shape of the portal. The points must define a planar convex polygon and must be in world coordinates.
void setTargetSector (Sector *sector)
 The Sector that is behind the portal and that is seen through the portal.
SectortargetSector ()
 The Sector that is behind the portal and that is seen through the portal.
const SectortargetSector () const
 The Sector that is behind the portal and that is seen through the portal.
bool isOpen () const
 If a Portal is closed or open. If the portal is closed then the camera cannot see the targetSector() through this portal.
void setIsOpen (bool is_open)
 If a Portal is closed or open. If the portal is closed then the camera cannot see the targetSector() through this portal.
