@Author Ralph Hauwert <code>@ax-student-ar-org-papervision3d-core-render-material-MaterialManager</code> (used internally) is a singleton that tracks all materials. Each time a material is created, the <code>@ax-student-ar-org-papervision3d-core-render-material-MaterialManager</code> registers the material for access in the render engine. 

  
          public class @ax-student-ar-org-papervision3d-core-render-material-MaterialManager
          {
                  private static var instance:@ax-student-ar-org-papervision3d-core-render-material-MaterialManager;
                  private var materials:Dictionary;
@ax-student-ar-org-papervision3d-core-render-material-MaterialManager singleton constructor

Allows for materials that animate or change (e.g., MovieMaterial) to be updated prior to the render
parameter: renderSessionData the data used in updating the material 

  
                  public function updateMaterialsBeforeRender(renderSessionData:RenderSessionData):void
                  {
                          var um:IUpdateBeforeMaterial;

                          }
                  }
Allows for materials that animate or change (e.g., MovieMaterial) to be updated after the render
parameter: renderSessionData the data used in updating the material 

  
                  public function updateMaterialsAfterRender(renderSessionData:RenderSessionData):void
                  {

                                  if(m is IUpdateAfterMaterial){
                                          um = m as IUpdateAfterMaterial;

                                  }
                          }
                  }
Registers a material 

  
                  public static function registerMaterial(material:MaterialObject3D):void
                  {
                          getInstance()._registerMaterial(material);
                  }
Unregisters a material 

  
                  public static function unRegisterMaterial(material:MaterialObject3D):void
                  {
                          getInstance()._unRegisterMaterial(material);
                  }
Returns a singleton instance of the <code>@ax-student-ar-org-papervision3d-core-render-material-MaterialManager</code> 

  
                  public static function getInstance():@ax-student-ar-org-papervision3d-core-render-material-MaterialManager
                  {
