animation constraint
Converts an object's position animation (animated position parameters) to path animation (animation along the path of a curve). The conversion is done by plotting the position animation into a curve (see the PlotCurve command). The object is then path-constrained to the new curve, and the constraint's percentage parameter is keyed at each frame step to create the path animation (see the ApplyPath command). The original position animation is deleted.
ConvertPosAnimToPath( [InputObjs], [Name], [StartTime], [EndTime], [StepFrame] ); |
| Parameter | Type | Description |
|---|---|---|
| InputObjs | String | List of objects with
position animation
Default Value: Selected objects |
| Name | String | Name to give to the plotted curve
Default Value: "Path" |
| StartTime | Double | First frame to convert
Default Value: 0 |
| EndTime | Double | Last frame to convert
Default Value: 0 |
| StepFrame | Double | Number of frames for each step
Default Value: 1 |
