Detailed Description

A Geode is a "geometry node", that is, a leaf node on the scene graph that can have "renderable things" attached to it. In OSG, renderable things are represented by objects from the Drawable class, so a Geode is a Node whose purpose is grouping Drawables.

Constructor & Destructor Documentation

osg::Geode::Geode ( )

osg::Geode::Geode	(	const Geode &	,

Member Function Documentation

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

virtual

Add a Drawable to the Geode. If drawable is not NULL and is not contained in the Geode then increment its reference count, add it to the drawables list and dirty the bounding sphere to force it to be recomputed on the next call to getBound().

Parameters

drawable The Drawable to be added to the Geode.

Returns: true for success; false otherwise.

Reimplemented in osg::Billboard.

virtual Geode* osg::Geode::asGeode ( )

inlinevirtual

Convert 'this' into a Geode pointer if Node is a Geode, otherwise return 0. Equivalent to dynamic_cast<Geode*>(this).

Reimplemented from osg::Node.

virtual const Geode* osg::Geode::asGeode ( ) const

inlinevirtual

convert 'const this' into a const Geode pointer if Node is a Geode, otherwise return 0. Equivalent to dynamic_cast<const Geode*>(this).

Reimplemented from osg::Node.

void osg::Geode::compileDrawables ( RenderInfo & renderInfo )

Compile OpenGL Display List for each drawable.

virtual BoundingSphere osg::Geode::computeBound ( ) const

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 a given 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.

Drawable* osg::Geode::getDrawable ( unsigned int i )

inline

Return the Drawable at position i.

Referenced by osgUtil::Simplifier::apply().

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

inline

Return the Drawable at position i.

unsigned int osg::Geode::getDrawableIndex ( const Drawable * drawable ) const

inline

Get the index number of drawable.

Returns: A value between 0 and getNumDrawables()-1 if drawable is found; if not found, then getNumDrawables() is returned.

const DrawableList& osg::Geode::getDrawableList ( ) const

inline

Get the list of drawables.

unsigned int osg::Geode::getNumDrawables ( ) const

inline

Return the number of Drawables currently attached to the Geode.

Referenced by osgUtil::Simplifier::apply().

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

virtual void osg::Geode::releaseGLObjects ( osg::State * = 0 ) const

virtual

If State is non-zero, this function releases any associated OpenGL objects for the specified graphics context. Otherwise, releases OpenGL objects for all graphics contexts.

Reimplemented from osg::Node.

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

virtual

Remove a Drawable from the Geode. Equivalent to removeDrawable(getDrawableIndex(drawable).

Parameters

drawable The drawable to be removed.

Returns: true if at least one Drawable was removed. false otherwise.

Reimplemented in osg::Billboard.

virtual bool osg::Geode::removeDrawables	(	unsigned int	i,
		unsigned int	numDrawablesToRemove = `1`
	)

virtual

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

Parameters

i	The index of the first `Drawable` to remove.
numDrawablesToRemove	The number of `Drawable` to remove.

Returns: true if at least one Drawable was removed. false otherwise.

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

virtual

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

virtual void osg::Geode::resizeGLObjectBuffers ( unsigned int maxSize )

virtual

Resize any per context GLObject buffers to specified size.

Reimplemented from osg::Node.

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

virtual

Set Drawable at position i. 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.

Returns: true if set correctly, false on failure (if node==NULL || i is out of range).

virtual void osg::Geode::setThreadSafeRefUnref ( bool threadSafe )

virtual

Set whether to use a mutex to ensure ref() and unref() are thread safe.

Reimplemented from osg::Node.
