Detailed Description

ProxyNode.

Member Typedef Documentation

typedef std::vector<std::string> osg::ProxyNode::FileNameList

Member Enumeration Documentation

enum osg::ProxyNode::CenterMode

Modes which control how the center of object should be determined when computed which child is active.

Enumerator:

USE_BOUNDING_SPHERE_CENTER
USER_DEFINED_CENTER

Constructor & Destructor Documentation

osg::ProxyNode::ProxyNode ( )

osg::ProxyNode::ProxyNode	(	const ProxyNode &	,
		const CopyOp &	copyop = `CopyOp::SHALLOW_COPY`
	)

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual osg::ProxyNode::~ProxyNode ( ) [inline, protected, virtual]

Member Function Documentation

virtual bool osg::ProxyNode::addChild	(	Node *	child,
		const std::string &	filename
	)			`[virtual]`

virtual bool osg::ProxyNode::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 BoundingSphere osg::ProxyNode::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.

void osg::ProxyNode::expandFileNameListTo ( unsigned int pos ) [protected]

const Vec3& osg::ProxyNode::getCenter ( ) const [inline]

return the ProxyNode center point.

CenterMode osg::ProxyNode::getCenterMode ( ) const [inline]

Get how the center of object should be determined when computed which child is active.

const std::string& osg::ProxyNode::getDatabasePath ( ) const [inline]

Get the database path used to prepend to children's filenames.

const std::string& osg::ProxyNode::getFileName ( unsigned int childNo ) const [inline]

unsigned int osg::ProxyNode::getNumFileNames ( ) const [inline]

float osg::ProxyNode::getRadius ( ) const [inline]

Get the object-space radius of the volume enclosed by the ProxyNode.

osg::ProxyNode::META_Node	(	osg	,
		ProxyNode
	)

virtual bool osg::ProxyNode::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::ProxyNode::setCenter ( const Vec3 & center ) [inline]

Sets the object-space point which defines the center of the osg::ProxyNode. center is affected by any transforms in the hierarchy above the osg::ProxyNode.

void osg::ProxyNode::setCenterMode ( CenterMode mode ) [inline]

Set how the center of object should be determined when computed which child is active.

void osg::ProxyNode::setDatabasePath ( const std::string & path )

Set the database path to prepend to children's filenames.

void osg::ProxyNode::setFileName	(	unsigned int	childNo,
		const std::string &	filename
	)			`[inline]`

void osg::ProxyNode::setRadius ( float radius ) [inline]

Set the object-space reference radius of the volume enclosed by the ProxyNode. Used to detmine the bounding sphere of the ProxyNode in the absense of any children.

virtual void osg::ProxyNode::traverse ( NodeVisitor & nv ) [virtual]

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

Reimplemented from osg::Group.
