Constructor & Destructor Documentation

Geode::Geode  ) 
 

Geode::Geode const Geode ,
const CopyOp copyop = CopyOp::SHALLOW_COPY
 

Copy constructor using CopyOp to manage deep vs shallow copy.

Geode::~Geode  )  [protected, virtual]
 


Member Function Documentation

bool 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 Geode::compileDrawables State state  ) 
 

compile OpenGL Display List for each drawable.

bool 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 
 

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

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

bool 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.

bool 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.

bool 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.
