It has the same attributes as a Light node, with the addition of a directional vector to specify the direction in which the light shines. A directional light has parallel light rays that travel in one direction along the specified vector. Directional light contributes to diffuse and specular reflections, which in turn depend on the orientation of an object's surface but not its position. A directional light does not contribute to ambient reflections.<P><P><HR><P><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%"
