virtual bool addGeoSet( GeoSet *gset )

Add GeoSet 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.

virtual bool addGeoSet(GeoSet *gset, const Vec3& pos)

Add GeoSet to Geode at position pos.

virtual bool removeGeoSet( GeoSet *gset )

Remove GeoSet and associated position from Billboard.

Add GeoSet 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.

virtual bool addGeoSet(GeoSet *gset, const Vec3& pos)

Add GeoSet 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.

virtual bool removeGeoSet( GeoSet *gset )

Remove GeoSet 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.
