[vtkusers] set up position of vtkImplicitPlaneWidget

[ChenDawnWind]

You could modify the vtkImplicitPlaneRepresentation of the widget, initial the plane then you could get what you want.Codes below are the pieces of the whole codes. Full example in :http://www.cnblogs.com/dawnWind/archive/2013/05/04/3D_11.html// set up representation for vtkImplicitPlaneWidget2 
    // you could set the normal and origin with the value you want 
    vtkSmartPointer<vtkImplicitPlaneRepresentation> rep = 
    vtkSmartPointer<vtkImplicitPlaneRepresentation>::New();
    rep->SetPlaceFactor(1.25); // This must be set prior to placing the widget
    rep->PlaceWidget(coneSkinActor->GetBounds());
#ifndef SET_VALUE
    rep->SetNormal(measureNormal);
    rep->SetOrigin(point3);
#endif
    vtkSmartPointer<vtkImplicitPlaneWidget2> implicitPlaneWidget = vtkImplicitPlaneWidget2::New();
    implicitPlaneWidget->SetInteractor(iren);
    // this set the representation for the widget thus the normal and origin is transfer to the widget
    implicitPlaneWidget->SetRepresentation(rep);

Subject: [vtkusers] set up position of vtkImplicitPlaneWidget

I am trying to use vtkImplicitPlaneWidget and it is located in the middle of outline frame by default. I can use mouse to move the plane. What is the function I can use to set up an arbitrary position of the plane when it is initialized, or to move the position by program rather than the built-in mouse event function?
