<div class="nodescription">no description available, TAbstractLightNode description follows</div><p>
Base class for all VRML / X3D light nodes.

<p>Note that even the old VRML 1.0 light nodes inherit from this. Although they interpret some bits differently (&quot;ambientIntensity&quot; &lt; 0 has special meaning). But most of the fields behave identically, they only have different default values.</p>
