typedef std::vector< ref_ptr<Drawable> > DrawableList

Geode()

Geode(const Geode&, const CopyOp& copyop=CopyOp::SHALLOW_COPY)

Copy constructor using CopyOp to manage deep vs shallow copy

META_Node(osg, Geode)

virtual bool addDrawable( Drawable* drawable )

Add Drawable to Geode. If gset is not NULL and is not contained in Geode then increment its reference count, add it to the drawables list and dirty the bounding sphere to force it to recompute on next getBound() and return true for success. Otherwise return false.

virtual bool removeDrawable( Drawable* drawable )

Remove Drawable from Geode. Equivalent to setDrawabke(getDrawableIndex(orignChild),node), see docs for setNode for futher details on implementation.

virtual bool removeDrawable(unsigned int i, unsigned int numDrawablesToRemove=1)

Remove drawable(s) from the specified position in Geode's drawable list

virtual bool replaceDrawable( Drawable* origDraw, Drawable* newDraw )

Replace specified Drawable with another Drawable. Equivalent to setDrawable(getDrawableIndex(orignChild),node), see docs for setDrawable for futher details on implementation.

virtual bool setDrawable( unsigned int i, Drawable* drawable )

set drawable at position i. return true if set correctly, false on failure (if node==NULL || i is out of range). Decrement the reference count origGSet and increments the reference count of newGset, and dirty the bounding sphere to force it to recompute on next getBound() and returns true. If origDrawable is not found then return false and do not add newGset. If newGset is NULL then return false and do not remove origGset.

inline unsigned int getNumDrawables() const

return the number of drawable's

inline Drawable* getDrawable( unsigned int i )

return drawable at position i

inline const Drawable* getDrawable( unsigned int i ) const

return drawable at position i

inline bool containsDrawable(const Drawable* gset) const

return true if drawable is contained within Geode

inline unsigned int getDrawableIndex( const Drawable* node ) const

Get the index number of drawable, return a value between 0 and _drawablessize()-1 if found, if not found then return _drawablessize()

void compileDrawables(State& state)

compile OpenGL Display List for each drawable

inline const BoundingBox& getBoundingBox() const

return the Geode's bounding box, which the union of all the bounding boxes of the geode's drawables
