Put this line at the end and see if it does anything.

I'm using a button to show/disappear an actor. 


Here's the code:

 

vtkCubeSource *cubo = vtkCubeSource::New();
    cubo->SetXLength(14);
    cubo->SetYLength(14);
    cubo->SetZLength(14);
    cubo->SetCenter(a/2,b/2,c/2);

  vtkPolyDataMapper *cuboMapper = vtkPolyDataMapper::New();
    cuboMapper->SetInput(cubo->GetOutput());

  vtkActor *cubo1 = vtkActor::New();
    cubo1->SetMapper(cuboMapper);
    cubo1->GetProperty()->SetColor(0.52, 0.27, 0);
    cubo1->GetProperty()->SetAmbient(0.2);
    cubo1->GetProperty()->SetDiffuse(0.3);
    cubo1->GetProperty()->SetSpecular(0.8);

 

if  (tbnCubo->Down) {                     // the button is down = the cube appears
    VTK3->GetRenderer()->AddActor(cubo1);

}

else {                                           // the button is up = the cube disappears 
    VTK3->GetRenderer()->RemoveActor(cubo1);
    VTK3->GetRenderer()->RemoveViewProp(cubo1);
    VTK3->GetRenderer()->Clear();

}

cubo->Delete();
cuboMapper->Delete();
cubo1->Delete();

VTK3->Invalidate();


When the button is up the actor does not disappear.

Just a dumb question : is your outlineActor the same at each call or not ? … could you please provide us with more sourcecode (t least the code before your condition …) ?
Fred.

Hello All,
 

How do I remove an individual actor from the scene? My code does not work. Someone help me? Thanks.
 
if  (tbnIniciar->Down) {
  VTK3->GetRenderer()->AddActor(outlineActor);
  }
 
else {
    VTK3->GetRenderer()->RemoveActor(outlineActor);
    VTK3->GetRenderer()->RemoveViewProp(outlineActor);
    VTK3->GetRenderer()->Clear();
   }
 
VTK3->Invalidate();
