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.


c } c } alpha

Interpolation control value.


c } c } 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.


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