The interpolation of an FCurve determines how values are evaluated between its FCurveKeys. This is very similar to the siFCurveKeyInterpolation enum.
| Constant | Value | Description |
|---|---|---|
| siDefaultInterpolation | 0 | Existing function |
| siConstantInterpolation | 1 | Constant function |
| siLinearInterpolation | 2 | Linear function |
| siCubicInterpolation | 3 | Bezier cubic function |
