# Vrml_DirectionalLight Class Reference

defines a directional light node of VRML specifying
properties of lights.
This node defines a directional light source that illuminates
along rays parallel to a given 3-dimentional vector
Color is written as an RGB triple.
Light intensity must be in the range 0.0 to 1.0, inclusive.
