By view we understand osg::View or SceneView instance and their associated
Camera. Typical osg application has one or more such views. View Dependent
Shadow techniques manage shadow generation for them.
View Dependent Shadow techniques are used to optimize shadow algorithms for
part of the scene seen on the view. If rest of the scene is behind view
frustum, there is no sense in computing shadows for it. Since in practice we
often use 3d databases extending far beyond current camera frustum View
Dependent Shadow approach may produce much better shadows.

Conceptually ViewDependentShadowTechnique is similar to osgSim::OverlayNode.

But ViewDependentShadowTechnique is intended as foundation layer for all

HOW IT WORKS:
ViewDependendentShadowTechnique is derived from osgShadow::ShadowTechnique
and as such overrides virtual methods of osgShadow::ShadowTechnique.

ViewDependendentShadowTechnique::cull is the only osgShadow::ShadowTechnique
method where ViewDependendentShadowTechnique does something significant:

It identifies View. CullVisitor ptr is used as View identificator.

In practice we do not check and interpret what are actual Views and SceneViews
set up by application. We focus on Camera and CullVisitors as a identificators

unique CullVisitor used to cull the scene in every frame.
Based on CullVisitor ptr passed to cull method, associated Technique::ViewData

To support creation of classes derived from ViewDependentShadowTechnique it
was neccessary to provide mechanism to override ViewData and allow for
initialization of new derived ViewData objects. Creation and initialization
is performed when ViewDependendentShadowTechnique::cull gets called with
CullVistor ptr which does not yet have associated ViewData object. When it
happens, virtual initViewDependentData method is called to give
derived techniques a chance to allocate and iniitalize its specific
resources as new ViewData derived instance. In practice initViewDependentData

happens, virtual initViewDependentData method is called to give
derived techniques a chance to allocate and iniitalize its specific
resources as new ViewData derived instance. In practice initViewDependentData
in derived techniques should look the same as in base class so as a convenience
it was defined as META_ViewDependentShadowTechnique macro. Derived techniques
use this macro to override initViewDependentData method for their usage.
