Hi, I’m viewing STL using C # RenderWindowControl.  
I want to erase the display of the model after loading and watching the model, but I do not know how.  
Would you like some advice on how to clear the model display from RenderWindowControl?

//— code to display STL model —//  
// 表示させたい3Dモデルファイル  
reader.SetFileName(stlOfd.FileName);  
// Mapperにオブジェクトを写像する  
mapper.SetInputConnection(reader.GetOutputPort());  
// ActorにMapperをセットする  
actor.SetMapper(mapper);  
// 描画ウィンドウにActorを追加する  
renderWindowControl1.RenderWindow.GetRenderers().GetFirstRenderer().AddActor(actor);
