Detailed Description

This is a pure virtual class. Subclasses of this class need to implement placerImplementation.

---

Constructor & Destructor Documentation

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

Copy constructor using CopyOp to manage deep vs shallow copy.

Member Function Documentation

void LabelPlacer::augment (  osgView::SpaceManager *  spaceManager, const osgExtension::MatrixEstimate &  MVPW, const osg::Vec3Array *  vertices, osg::NodePath &  path )

place the labels for this object. this function calls placerImplementation for the actual computation. Parameters: spaceManager  a pointer to the space manager MVPW  the matrix estimate for this node vertices  list of vertices of the object path  the path on the scene graph
