Detailed Description
The GeneralDirectionalLight node defines a directional light source that illuminates along rays parallel to a given 3-dimensional vector.
It allows different values for the ambient, specular and diffuse color parts of the light specification.
The direction field specifies the direction vector of the illumination emanating from the light source in the local coordinate system. Light is emitted along parallel rays from an infinite distance away. A directional light source illuminates only the objects in its enclosing parent group. The light may illuminate everything within this coordinate system, including all children and descendants of its parent group. The accumulated transformations of the parent nodes affect the light.
GeneralDirectionalLight nodes do not attenuate with distance.
