Hi, thanks for the reply.<br>Actually the setUsermatrix is what I have done...but still no results in my screen. This is my code:<br><br> vtkActor *tmpAct; <br> <br> _pickedActors = _picker->GetActors();<br> _pickedActors->InitTraversal();<br> tmpAct = _pickedActors->GetNextItem();<br><br>while (tmpAct != 0){<br><br> tmpAct->SetUserMatrix(m);<br> tmpAct = _pickedActors->GetNextItem(); <br> }<br><br>where _pickedActors is a vtkActorCollections and _picker is a vtkPicker. m is a vtkMatrix4x4 that I initialised as<br>1 0 0 0<br>0 1 0 0 <br>0 0 1 55<br>0 0 0 1<br><br>so I would see a translation of 55 in the Z.<br><br>GC.<br><br><hr id="stopSpelling">Date: Tue, 31 Mar 2009 12:30:14 +0200<br>From: J.S.Wijnhout@lumc.nl<br>To: vtkusers@vtk.org<br>Subject: Re: [vtkusers] vtkTransformFilter<br><br>

</style>Hi,<br>
<br>
You solution doesn't work because do you not connect the output of trF to the mapper of the actor.
Btw, if you want to apply a user defined transformation matrix to your actor, simply use:
vtkActor::SetUserMatrix.<br>

Hi everybody,<br><br>I
have an object picked usint VTkpicker....and I can recover its actor. now, I also define a
vtkMatrix4x4 which is a rigid transformation matrix.<br>I want to apply that transformation to the object and I wrote this:<br><br>vtkTransform *tr = vtkTransform::New();<br> tr->SetMatrix(m);<br> tr->Update();<br><br> vtkTransformFilter *trF = vtkTransformFilter::New();<br> trF->SetInput(tmpAct->GetMapper()->GetInput());<br> trF->SetTransform(tr);<br> trF->Update();<br><br>where tmpAct is the actor picked by the picker.<br>So I thought that after refreshing the visualization I should see the object modified, but it doesn't....so where's the trick?<br><br>Kind Regards.<br>Giancarlo<br><br><hr>La tua immagine personale dinamica per Messenger? <a href="http://clk.atdmt.com/GBL/go/136430519/direct/01/">Creala gratis con Avatar Studio!</a><br /><hr />Scopri tutte le novità. <a href='http://clk.atdmt.com/GBL/go/136422322/direct/01/' target='_new'>Scarica Messenger 2009!</a></body>
