Test keys with same value. A CoordinateInterpolator node is used to change the coordinate location 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. The keys for the CoordinateInterpolator are set to values [ 0, 0.25, 0.5, 0.5, 0.5, 0.75, 1.0 ], and the keyValues for the 8 vertices are set to [ -1 1 1, -1 -1 1, 1 1 1, 1 -1 1, 1 1 -1, 1 -1 -1, -1 1 -1, -1 -1 -1 -2 1 1, -2 -1 1, 2 1 1, 2 -1 1, 2 1 -1, 2 -1 -1, -2 1 -1, -2 -1 -1 -1 1 1, -1 -1 1, 1 1 1, 1 -1 1, 1 1 -1, 1 -1 -1, -1 1 -1, -1 -1 -1 -1 1 2, -1 -1 2, 1 1 2, 1 -1 2, 1 1 -2, 1 -1 -2, -1 1 -2, -1 -1 -2 -1 1 1, -1 -1 1, 1 1 1, 1 -1 1, 1 1 -1, 1 -1 -1, -1 1 -1, -1 -1 -1 -1 2 1, -1 -2 1, 1 2 1, 1 -2 1, 1 2 -1, 1 -2 -1, -1 2 -1, -1 -2 -1 -1 1 1, -1 -1 1, 1 1 1, 1 -1 1, 1 1 -1, 1 -1 -1, -1 1 -1, -1 -1 -1 ] Because the three middel keys have the same value, the first and last identical key should serve as a limit for that key, and should result in the geometry expanding along the X axis, return to its original shape, then expand along the Y axis, then return to its original shape, in a 5 second time interval. The geometry should NOT expand along the Z axis.
