Reshaping the Plotline in the Function Editor

You can change the shape of the plotline in the Function Editor when you want to change how quickly an effect (such as rotation, scale or velocity) is applied to the peg and other elements attached to it.

The Function Editor provides pre-set reshape functions that you can apply to your plotline to change its shape. For example, if you wanted an effect to ease-in and ease-out, you could use one of the ease functions to change the plotline.

Constant: applies the value you have selected on the horizontal axis (y-axis) to the segment or plotline.
Ease in/out : applies a gradual acceleration to the beginning, and a gradual deceleration to the end, of the segment or plotline.
Extreme ease in/out :applies a more gradual acceleration to the beginning, and a more gradual deceleration to the end, of the segment or plotline.
Linear: applies a constant change to the segment or plotline.
Fast in/out : applies a fast acceleration to the beginning and end of the segment or plotline.
Extreme fast in/out : applies an even faster acceleration to the beginning and end of the segment or plotline.
Slow acceleration : applies a slow acceleration to the segment or plotline.
Slow deceleration : applies a fast acceleration to the segment or plotline.

You can also make changes to the shape of your plotline manually. However, when you use the pre-set functions in the Function Editor, Toon Boom Studio does the work for you!

To reshape the plotline in the Function Editor using the Reshape Functions:

1. Click the Select button in the Tools panel.

2. Select the segment of the plotline you want to reshape.

If you want to reshape only one segment, click anywhere along the segment.
If you want to reshape all segments on the plotline, click anywhere on the plotline.

3. To create segments on the plotline, you must add keyframes.

4. Decide if you want to apply a change to a segment or the whole plotline.

To reshape only the segment you selected, select any of the options in the Reshape menu.
To reshape all segments in the plotline with the same function, press [Shift] and select one of the options in the Reshape menu.

To manually reshape the plotline in the Function Editor:

1. Click a keyframe on the plotline. Handles appear on either side of the point you select.

2. Decide if you want to move both handles independently of each other or together.

To move a handle independently of the other handle, drag the point at the end of the handle to its new position.
To move both handles together, press [Command] and drag the points to their new position.

The Left and Right Handle and Angle fields also display the position and the angle of the keyframes. You can also use these fields to set precise position/angles.
