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 Drawable
s.
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] |
virtual bool osg::Geode::addDrawable | ( | Drawable * | drawable | ) | [virtual] |
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()
.
true
for success; false
otherwise. Reimplemented in osg::Billboard.

virtual const Geode* osg::Geode::asGeode | ( | ) | const [inline, virtual] |
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::Group.
Reimplemented in osg::Billboard.
bool osg::Geode::containsDrawable | ( | const Drawable * | drawable | ) | const [inline] |
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
.
References osg::Drawable::asDrawable().
Referenced by osgUtil::Simplifier::apply().
const Drawable* osg::Geode::getDrawable | ( | unsigned int | i | ) | const [inline] |
Return the Drawable
at position i
.
References osg::Drawable::asDrawable().
unsigned int osg::Geode::getDrawableIndex | ( | const Drawable * | drawable | ) | const [inline] |
Get the index number of drawable
.
getNumDrawables()-1
if drawable
is found; if not found, then getNumDrawables()
is returned. unsigned int osg::Geode::getNumDrawables | ( | ) | const [inline] |
Return the number of Drawable
s currently attached to the Geode
.

virtual bool osg::Geode::removeDrawable | ( | Drawable * | drawable | ) | [virtual] |
Remove a Drawable
from the Geode
.
Equivalent to removeDrawable(getDrawableIndex(drawable)
.
drawable | The drawable to be removed. |
true
if at least one Drawable
was removed. false
otherwise. Reimplemented in osg::Billboard.

unsigned int | numDrawablesToRemove = 1 |

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 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.
true
if set correctly, false
on failure (if node==NULL || i is out of range). osg::BoundingBox osg::Geode::_bbox [mutable, protected] |
