FCurve.Extrapolation

Sets or returns the extrapolation type of the function curve as one of the siFCurveExtrapolation enum values.

For more information, see "FCurve Interpolation and Extrapolation" in the Softimage user guide.

C# Syntax

// get accessor

siFCurveExtrapolation rtn = FCurve.Extrapolation;

// set accessor

FCurve.Extrapolation = siFCurveExtrapolation;
