o Billboard()

o Billboard(const Billboard&, const CopyOp& copyop=CopyOp::SHALLOW_COPY)
Copy constructor using CopyOp to manage deep vs shallow copy

o META_Node(osg, Billboard)

ovoid setMode(Mode mode)
Set the billboard rotation mode.

oinline Mode getMode() const
Get the billboard rotation mode.

ovoid setAxis(const Vec3& axis)
Set the axis about which all the billboard's drawable rotate. Only utlized when mode==AXIAL_ROT

oinline const Vec3& getAxis() const
Get the axis about which all the billboard's drawable rotate.

ovoid setNormal(const Vec3& normal)
Set the normal which defines the billboard's drawable front face, when unrotated.

oinline const Vec3& getNormal() const
Get the normal of billboard's drawable front face.

oinline void setPos(unsigned int i, const Vec3& pos)
Set the position of specified drawable.

oinline const Vec3& getPos(unsigned int i) const
Get the position of specified drawable.

otypedef std::vector<Vec3> PositionList
PositionList represents a list of pivot points for each drawable

oinline PositionList& getPositionList()
Get the PositionList from the billboard

oinline const PositionList& getPositionList() const
Get a const PositionList from the billboard

ovirtual bool addDrawable( Drawable* gset )
Add Drawable to Billboard with default position(0,0,0); If gset not NULL and is not contained in Billboard then increment its reference count, and dirty the bounding box to cause it to recompute on next getBound() and return true for success. Otherwise return false.

ovirtual bool addDrawable(Drawable* gset, const Vec3& pos)
Add Drawable to Geode at position pos. If gset not NULL and is not contained in Billboard then increment its reference count, and dirty the bounding box to cause it to recompute on next getBound() and return true for success. Otherwise return false.

ovirtual bool removeDrawable( Drawable* gset )
Remove Drawable and associated position from Billboard. If gset is contained in Billboard then remove it from the geoset list and decrement its reference count, and dirty the bounding box to cause it to recompute on next getBound() and return true for success. If gset is not found then return false and do not the reference count of gset is left unchanged.
