DESCRIPTION

       This engine linearly interpolates between two 3D 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

     SoMFVec3f           input0
     SoMFVec3f           input1
          The engine linearly interpolates from input0 to input1.

METHODS

                         SoInterpolateVec3f()
          Constructor.
