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.
