<meta name='descriptioncontent='Test keys with same value. A NormalInterpolator node is used to change the normal vector at each vertex on a rectangular shaped IndexedFaceSet. The fraction_changed field of a TimeSensor node is used to control the keyframe animation of the normals. Because the three midde keys [0.5, 0.5, 0.5, 0.5 0.5] have the same value, the first and last identical key should serve as a limit for that key, and should result in NO vertical change in normals, hence the light will only appear to move horizontally in the XZ plane.'/>
