Hi Dženan,<br><br>Thank you for your reply. I think I get it.<br><br>Thank you very much.<br><br>Wenlong<br><br><div class="gmail_quote">2011/11/11 Dženan Zukić <span dir="ltr"><<a href="mailto:dzenanz@gmail.com">dzenanz@gmail.com</a>></span><br>
<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">From the <a href="http://www.vtk.org/doc/nightly/html/classvtkTransform.html" target="_blank">docs</a> I would say it concatenates. If you want to reset it just call Identity(), no need to delete.<br>

<br>If I do multiple transformation with the same vtkTransform object, would these transformation concatenate? For example, if I translate my actor as transform->Translate(10, 0), and then scale it again transform->Translate(20, 0). Would the result actor be moved on X direction by 30? What if the same situation happens in scale and rotate?<br>
<br>If it does concatenate, and I don't want it to be concatenate, should I delete the transform object and generate another one instead?<br><br>Thank you very much.<br><br>Best wishes<br>Long<br>
