DESCRIPTION
     SoInterpolate is the abstract base class for all interpolator engines. An
     interpolator engine linearly interpolates between two values, based on
     the alpha input value. The alpha value should be between 0.0 and 1.0. The
     interpolator engines derived from this class define the input fields that
     are to be interpolated.

INPUTS
     SoSFFloat           alpha
          Interpolation control value.


OUTPUTS
     (SoMFFloat)         output
          Interpolated value. The type of the output value is the same as the
          type of the input values, which is specified by the derived classes.


FILE FORMAT/DEFAULTS
     This is an abstract class. See the reference page of a derived class for
     the format and default values.
