Detailed Description

Simple node that renders a Geometry into a scene graph node. The coordinates of the geometry are explicit; there is no association with spatial reference or a map. You can use this object to create a geometry for use in a local tangent plane coordinate system.

Member Function Documentation

template<typename T >

T* osgEarth::Util::Annotation::GeometryNode::getOrCreateParent ( ) [inline]

Gets or creates a parent node for the internal draped node. Typically you would use this to install a Transform node atop the draped node.
