Object Model: FCurve.Extrapolation

FCurve.Extrapolation

Description

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;
