[vtkusers] The light of the vtkCamera

[Chunyan Jiang]

Dear all,
I set the camera as:
  Camera = vtkCamera::New();
  Camera->SetPosition(0,0,-100  );
  Camera->SetFocalPoint( 0,0,0 );
  Camera->SetThickness(2000);
  Camera->Dolly(0.15);

And I use this Camera to render the 3d object. When I rotate the object,
some time, I find the light is very dark. I almost can not see the detail of
the object. How can I set the camera or the light, so that the side of the
object towards the viewer is always bright?
Any help is appreciated!
