Constructor & Destructor Documentation

osg::Geode::Geode (   )

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

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual osg::Geode::~Geode (   )  [protected, virtual]

Member Function Documentation

virtual bool osg::Geode::addDrawable (  Drawable *  drawable  )  [virtual]

Add Drawable to Geode. If drawable 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. Reimplemented in osg::Billboard.

void osg::Geode::compileDrawables (  State &  state  )

compile OpenGL Display List for each drawable.

virtual bool osg::Geode::computeBound (   )  const [protected, virtual]

Compute the bounding sphere around Node's geometry or children. This method is automatically called by getBound() when the bounding sphere has been marked dirty via dirtyBound(). Reimplemented from osg::Node. Reimplemented in osg::Billboard.

bool osg::Geode::containsDrawable (  const Drawable *  gset  )  const [inline]

return true if drawable is contained within Geode.

const BoundingBox& osg::Geode::getBoundingBox (   )  const [inline]

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

const Drawable* osg::Geode::getDrawable (  unsigned int  i  )  const [inline]

return drawable at position i.

Drawable* osg::Geode::getDrawable (  unsigned int  i  )  [inline]

return drawable at position i.

unsigned int osg::Geode::getDrawableIndex (  const Drawable *  node  )  const [inline]

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

unsigned int osg::Geode::getNumDrawables (   )  const [inline]

return the number of drawables.

osg::Geode::META_Node (  osg  , Geode  )

virtual bool osg::Geode::removeDrawable (  unsigned int  i, unsigned int  numDrawablesToRemove = 1 )  [virtual]

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

virtual bool osg::Geode::removeDrawable (  Drawable *  drawable  )  [virtual]

Remove Drawable from Geode. Equivalent to setDrawable(getDrawableIndex(originChild),node), see docs for setNode for further details on implementation. Reimplemented in osg::Billboard.

virtual bool osg::Geode::replaceDrawable (  Drawable *  origDraw, Drawable *  newDraw )  [virtual]

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

virtual bool osg::Geode::setDrawable (  unsigned int  i, Drawable *  drawable )  [virtual]

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.
