Chapter 7 Keyframe Effects
• Continuity = +1.00
The path is already in the direction toward point 3 as it enters
keyframe point 2, but then reverts to the direction from point 1 as
it leaves. Thus the direction of the path is not continuous as it
passes the keyframe.

• Continuity = –1.00
In this case the direction of the path is again not continuous
through keyframe point 2, but this time the incoming direction is
that from point 1, and the outgoing direction is that toward point
3. Thus the effect of this setting is similar to setting the tension
to +1.00, but the speed through the keyframe point is different.
