FCurve.Fit
v5.1
Fits the FCurve within the specified time span. 'Fitting'
removes redundant keys while preserving the original shape of a
function curve.
Note: If the FCurve is locked or if any keys in the interval are
locked then the method raises an 'Access Denied' (E_ACCESSDENIED)
error.
FCurve.Fit( Object in_StartFrame, Object in_EndFrame, Double in_dFittingTolerance ); |
FCurve.Fit( [StartFrame], [EndFrame], [FittingTolerance] ); |
| Parameter | Type | Description |
|---|---|---|
| StartFrame | Variant | The start time of the range to fit. Must be less than the
EndFrame value.
Default Value: The first key frame on the fcurve or, if there are no keys, the PlayControl.In frame value. |
| EndFrame | Variant | The end time of the range to fit (in frames).
Default Value: The last key frame or, if there are no keys, the PlayControl.Out frame value. |
| FittingTolerance | Double | Adjusts the closeness of the fit (that is, Maximum distance
between the FCurve and the resulting fitted FCurve). Smaller values
will respect the original shape of the curve more by using more
keys, while larger values will use less keys and result in a fit
that deviates from the original curve. The value must be greater
than 0.
Default Value: 0.1 |

// Create a null
NewScene("", false);
var nullobj = Application.ActiveSceneRoot.AddNull();
// Use the Resample method to add keys to empty fcurves
nullobj.posx.AddFCurve().Resample();
nullobj.posy.AddFCurve().Resample();
var posxFC = nullobj.posx.Source;
var posyFC = nullobj.posy.Source;
Application.LogMessage( "posx curve : " + posxFC.GetNumKeys() );

// Fit the posx curve
posxFC.Fit();
Application.LogMessage( "fitted posx curve : " + posxFC.GetNumKeys() );
Application.LogMessage( "posy curve : " + posyFC.GetNumKeys() );
// Outputs:
//INFO : posx curve : 100
//INFO : posy curve : 100
//INFO : fitted posx curve : 2
//INFO : posy curve : 100
