CoordinateInterpolator

Definition : 

CoordinateInterpolator {
  eventIn      SFFloat set_fraction
  exposedField MFFloat key           []
  exposedField MFVec3f keyValue      []
  eventOut     MFVec3f value_changed
}

Explanation :

This node linearly interpolates among a set of MFVec3f value. This would be appropriate for interpolating Coordinate positions for a geometric morph. The number of coordinates in the keyValue field must be an integer multiple of the number of keyframes in the key field; that integer multiple defines how many coordinates will be contained in the value_changed events.
