out for their use. You might find, however, that the majority of animations you create
work best with simple TCB-adjusted curves.
Hermite splines have tangent control handles that allow you to control the shape of a
curve. Figure 6.52 shows a sequence of three keyframes with Hermite splines added to the
middle keyframe. Its handles are adjusted.
Figure 6.52 Hermite splines are added to the middle keyframe.These splines offer more control
than regular TCB splines.
Figure 6.52 shows three keyframes??”one low, one high, and one low again??”in a sort of bell
shape. However, the middle keyframe has a Hermite spline applied and the left handle of
it has been pulled down quite a bit. The figure shows how an adjustment to one keyframe

can have a drastic effect on the shape of a curve. You can do this by clicking and dragging
on the small purple handles that appear on a selected keyframe after the spline is added.
If you apply a Bezier curve, you acquire a different type of control than for a Hermite
spline. A Bezier spline is a variant of a Hermite spline and also shapes the curve.
