## siFCurveKeyInterpolation

### Description

Specifies the interpolation type for a specific key on an fcurve. The interpolation determines how the value is evaluated between FCurveKeys.

### C# Syntax

    siFCurveKeyInterpolation.siDefaultKeyInterpolation                          // 0
    siFCurveKeyInterpolation.siConstantKeyInterpolation                         // 1
    siFCurveKeyInterpolation.siLinearKeyInterpolation                           // 2
    siFCurveKeyInterpolation.siCubicKeyInterpolation                            // 3

Constant | Value | Description
--- | --- | ---
siDefaultKeyInterpolation | 0 | Existing function.
siConstantKeyInterpolation | 1 | Constant function
siLinearKeyInterpolation | 2 | Linear function
siCubicKeyInterpolation | 3 | Bezier cubic function
