Detailed Description

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.

Constructor & Destructor Documentation

osg::Switch::Switch

(

)

osg::Switch::Switch	(	const Switch &	,
		const CopyOp &	copyop = CopyOp::SHALLOW_COPY
	)

Copy constructor using CopyOp to manage deep vs shallow copy.

Member Function Documentation

osg::Switch::META_Node	(	osg	,
		Switch
	)

virtual void osg::Switch::traverse

(

NodeVisitor &

)

[virtual]

Traverse downwards : calls children's accept method with NodeVisitor.

Reimplemented from osg::Group.

void osg::Switch::setNewChildDefaultValue

(

bool

value

)

[inline]

bool osg::Switch::getNewChildDefaultValue

(

)

const [inline]

virtual bool osg::Switch::addChild

(

Node *

child

)

[virtual]

Add Node to Group.

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 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.

virtual bool osg::Switch::insertChild	(	unsigned int	index,
		Node *	child,
		bool	value
	)			[virtual]

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.

void osg::Switch::setValue	(	unsigned int	pos,
		bool	value
	)

bool osg::Switch::getValue

(

unsigned int

pos

)

const

void osg::Switch::setChildValue	(	const Node *	child,
		bool	value
	)

bool osg::Switch::getChildValue

(

const Node *

child

)

const

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).

bool osg::Switch::setSingleChildOn

(

unsigned int

pos

)

Set a single child on, switch off all other children.

void osg::Switch::setValueList

(

const ValueList &

values

)

[inline]

const ValueList& osg::Switch::getValueList

(

)

const [inline]

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.
