.PP 
The \fBSoShadowDirectionalLight\fP class is a node for setting up a directional light which casts shadows\&. 

Directional lights usually affect everything, but since it is not always feasible to use one shadow map for the entire scene graph\&. This node has some extra features to work around this\&.
.PP
It calculates the intersection between the current view volume and either the scene bounding box, or the bounding box provided in this node\&. The shadows are only calculated for this volume\&. This means that you'll get more detailed shadows as you zoom in on items in the scene graph\&.
.PP
In addition, you can set the maximum distance from the camera which will be shaded with shadows\&. Think of this a new far plane for the camera which only affects shadows\&.
.PP
As with \fBSoShadowSpotLight\fP, it's possible to optimize further by setting your own shadow caster scene graph in the shadowMapScene field\&.
.PP
The example scene graph below demonstrates how you can use this node to create shadows on a large number of objects, and still get decent precision when zooming in\&. To further reduce the volume covered by the shadow map, you can set \fImaxShadowDistance\fP to some number > 0\&. This is the distance from the camera where shadows will be visible\&.
