[vtkusers] java repaint?

[ekaditya]

Hello David and Prabhath,
thank you so much for your response. :))

the problem with image STL file done, which is the second STL image 
replacing the first STL image.
so there is olny one object in window, but there's antoher problem raising, 
the camera is still following the first STL image.
i mean, when i interact with the second STL image, the first STL image is 
still there.
the fisrt STL image only cleared to the background color.. :(

i already try to use following code, hopefully it will reset the camera, and 
turn it to the second STL image..

public void open(String fileName)
{
renderer = renWin.GetRenderer();
renderer.RemoveActor(actor);
renderer.SetBackground(0.1, 0.2, 0.4);
 renderer.ResetCameraClippingRange();
 renderer.ResetCamera();
 renderer.InteractiveOff();

this.validate(); //extends JPanel
this.repaint();
renWin.validate();
renWin.repaint();

vtkSTLReader reader = new vtkSTLReader();
reader.SetFileName(fileName);

vtkPolyDataMapper mapper = new vtkPolyDataMapper();
mapper.SetInput(reader.GetOutput());

actor = new vtkActor();
actor.SetMapper(mapper);

renderer.AddActor(actor);
}

is there any way, so that the second STL file replacing first STL image, and 
the camara also?

thanks for your response..
