DESCRIPTION

       This  engine linearly interpolates between two floating-point values, based on the alpha input value. The
       alpha value should be between 0.0 and 1.0.

       The input fields can have multiple  values,  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

     SoMFFloat           input0
     SoMFFloat           input1
          The engine linearly interpolates from input0 to input1.

METHODS

                         SoInterpolateFloat()
          Constructor.
