<p class="ecxMsoNormal" style="margin-bottom: 12pt;"><span style="font-size: 10pt; font-family: 'Verdana','sans-serif';">Hello vtkUsers,<br>
<br>
I'm back with, I'm sure, a "so-many-times-asked" question:<br>
<br>
I've a camera and a file with a sequence of postions that the camera takes.<br>
Now, I'm using the QVTKWidget for rendering my scene.<br>
<br>
I call:<br>
<br>
vtkSmartPointer<vtkCamera>tmpCam =
this->mp_VTKwidget->GetRenderWindow()->GetRenderers()->GetFirstRenderer()->GetActiveCamera();<br>
tmpCam->SetViewUp((*mI_vtkCamera)->GetViewUp());<br>
tmpCam->SetPosition((*mI_vtkCamera)->GetPosition());<br>
tmpCam->SetFocalPoint((*mI_vtkCamera)->GetFocalPoint());<br>
<br>
to update the current renderer camera position.<br>
But What I'm not seeing is an update of the view untile I click with the mouse
inside the QVTKWidget (mp_VTKwidget).<br>
so my question is HOW to update/refresh the view automatically?<br>
<br>
I tried the method Render() of the vtkRenderer but it's apparently
unseccessful.<br>
<br>
Many thanks.<br>
Giancarlo</span></p>
