Switch is a Group node that allows switching between children.
Typical uses would be for objects which might need to be rendered differently at different times, for instance a switch could be used to represent the different states of a traffic light.
typedef std::vector<bool> osg::Switch::ValueList |
osg::Switch::Switch | ( | ) |
Copy constructor using CopyOp to manage deep vs shallow copy.
virtual osg::Switch::~Switch | ( | ) | [inline, protected, virtual] |
virtual bool osg::Switch::addChild | ( | Node * | child | ) | [virtual] |
If node is not NULL and is not contained in Group then increment its reference count, add it to the child list and dirty the bounding sphere to force it to recompute on next getBound() and return true for success. Otherwise return false. Scene nodes can't be added as child nodes.
Reimplemented from osg::Group.
virtual bool osg::Switch::addChild | ( | Node * | child, |
bool | value | ||
) | [virtual] |
virtual const Switch* osg::Switch::asSwitch | ( | ) | const [inline, virtual] |
virtual Switch* osg::Switch::asSwitch | ( | ) | [inline, virtual] |
virtual BoundingSphere osg::Switch::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.
bool osg::Switch::getChildValue | ( | const Node * | child | ) | const |
bool osg::Switch::getNewChildDefaultValue | ( | ) | const [inline] |
bool osg::Switch::getValue | ( | unsigned int | pos | ) | const |

virtual bool osg::Switch::insertChild | ( | unsigned int | index, |
Node * | child, | ||
bool | value | ||
) | [virtual] |
virtual bool osg::Switch::insertChild | ( | unsigned int | index, |
Node * | child | ||
) | [virtual] |
Insert Node to Group at specific location.
The new child node is inserted into the child list before the node at the specified index. No nodes are removed from the group with this operation.
Reimplemented from osg::Group.
osg::Switch::META_Node | ( | osg | , |
Switch | |||
) |
virtual bool osg::Switch::removeChildren | ( | unsigned int | pos, |
unsigned int | numChildrenToRemove | ||
) | [virtual] |
Remove children from Group.
Note, must be override by subclasses of Group which add per child attributes.
Reimplemented from osg::Group.
bool osg::Switch::setAllChildrenOff | ( | ) |
Set all the children off (false), and set the new default child value to off (false).
bool osg::Switch::setAllChildrenOn | ( | ) |
Set all the children on (true), and set the new default child value to on (true).
void osg::Switch::setChildValue | ( | const Node * | child, |
bool | value | ||
) |
void osg::Switch::setNewChildDefaultValue | ( | bool | value | ) | [inline] |
bool osg::Switch::setSingleChildOn | ( | unsigned int | pos | ) |
Set a single child on, switch off all other children.
void osg::Switch::setValue | ( | unsigned int | pos, |
bool | value | ||
) |
void osg::Switch::setValueList | ( | const ValueList & | values | ) | [inline] |
virtual void osg::Switch::traverse | ( | NodeVisitor & | ) | [virtual] |
Traverse downwards : calls children's accept method with NodeVisitor.
Reimplemented from osg::Group.
