DESCRIPTION
     This engine linearly interpolates between two 4D vectors, based on the
     alpha input value. The alpha value should be between 0.0 and 1.0.

     The input fields can have multiple vectors, allowing the engine to
     interpolate several objects in parallel. One of the inputs may have more
     values than the other. In that case, the last value of the shorter input
     will be repeated as necessary.

INPUTS
     SoMFVec4f		 input0
     SoMFVec4f		 input1
	  The engine linearly interpolates from input0 to input1.

FUNCTIONS
     SoInterpolateVec4f *  SoInterpV4fCreate()
	  Constructor.

FILE FORMAT/DEFAULTS

	  alpha	  0
	  input0  0 0 0 0
	  input1  0 0 0 0
