<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>Interface for dynamic creation of scene nodes. </p>
<p>To be able to add custom scene nodes to Irrlicht and to make it possible for the scene manager to save and load those external scene nodes, simply implement this interface and register it in you scene manager via <a class="el" href="classirr_1_1scene_1_1_i_scene_manager.html#a75ac9315def74ae5e26a2d6a2f5a38e9" title="Adds a scene node factory to the scene manager.">ISceneManager::registerSceneNodeFactory</a>. Note: When implementing your own scene node factory, don't call ISceneNodeManager::grab() to increase the reference counter of the scene node manager. This is not necessary because the scene node manager will <a class="el" href="classirr_1_1_i_reference_counted.html#a2b7a035532e5f409ca9482dab79185f4" title="Grabs the object. Increments the reference counter by one.">grab()</a> the factory anyway, and otherwise cyclic references will be created and the scene manager and all its nodes won't get deallocated. </p>
