Modifying Interpolation

Once you create keyframes for a channel, you can use interpolation to determine the channel values for the in-between frames. The appearance of the animation in the Animation Editor depends on the interpolation method used. In the Animation Editor, the interpolation method is represented by the shape of the curve that joins the keyframes. You can set the interpolation for an entire curve or for individual keyframes.

The following interpolation methods are supported:

• Constant (key values do not change in time between keys, tangents are absent)
• Linear (straight interpolation between keys, tangents are absent)
• Bezier (spline interpolation, you can edit the tangent length and orientation)

(a) Bezier  (b) Linear  (c) Constant  

To set the interpolation method for an individual keyframe or an entire curve using the Animation tab Property area or the Animation Editor view controls:

1. Select the keyframe(s) for which you want to change the interpolation.
2. Select Interpolation and select the interpolation method.
