if you look at the implementation of osgShadow, in particular the
osg::ShadowMap class you will see how to render the scene from the light's
point of view for the purpose of creating a depth map. The depth map is
then later used when rendering the main view, for superimposing a shadow.
Warning: the default behavior turns on backface culling and only enables
the back faces for rendering. This may not be what you want - but it's easy
enough to change.

Hello.
Lets say there is cessna as a child in LightSource group.
LightSource has 1 light.
What i want to do is to get the depth map from light's point of view.
How can i do this ?
I am thinking of placing a Camera as a child in LightSource.
This camera will look at exactly the same direction as the light and
will also has the same position.
Is this the right way to do it ?
( I know how to make camera render to texture)
Thank you for your time.
