3-D Digital Effects Concepts
With continuity set to -1.0, the paths between the keyframes become
straight lines, accelerating into the keyframe and decelerating as it leaves
the keyframe (
Figure 65 ).

Bias Control
The BIAS control determines whether the path will be pulled towards the
previous or the following keyframe. With extreme settings, all of the
biasing will occur either before or after KF2. With bias set to 0 (zero), the
curve through the keyframe is gentle as shown in
Figure 66 .
Note A Tension vector must be present for Bias control to be available.
