Member Function Documentation

operator()()

void WLabelsTransformCallback::operator() ( osg::Node *  node, osg::NodeVisitor *  nv  )

virtual

Callback method called by the NodeVisitor when visiting a node.

Change the matrix according to the properties.

Parameters

node	The node this callback is connected to. Should be a MatrixTransform node.
nv	The node visitor which performs the traversal. Should be an update visitor.
