Geode is a "geometry node", that is, a leaf node on the scene graph that can have "renderable things" attached to it.

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.
| typedef std::vector< ref_ptr<Drawable> > osg::Geode::DrawableList |
| osg::Geode::Geode | ( | ) |
Copy constructor using CopyOp to manage deep vs shallow copy.

| osg::Geode::META_Node | ( | osg | , | |

| 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 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.
| virtual bool osg::Geode::removeDrawables | ( | unsigned int | i, | |
| unsigned int | numDrawablesToRemove = 1 | |||
| ) | [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). | unsigned int osg::Geode::getNumDrawables | ( | ) | const [inline] |
| const Drawable* osg::Geode::getDrawable | ( | unsigned int | i | ) | const [inline] |
Return the Drawable at position i.
| bool osg::Geode::containsDrawable | ( | const Drawable * | gset | ) | const [inline] |
| 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. | const DrawableList& osg::Geode::getDrawableList | ( | ) | const [inline] |
Get the list of drawables.
| void osg::Geode::compileDrawables | ( | RenderInfo & | renderInfo | ) |
Compile OpenGL Display List for each drawable.
| 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.
| 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.
