CURVE — Provides three knobs to control the three
parameters of the path vector: TENSION, CONTINUITY, and
BIAS. These knobs act on the vector parameters to adjust the
path into (entry) and out of (exit) the keyframe. The path
through KF2 is parallel with an imaginary line drawn
between KF1 and KF2.
TENSION — Controls the length of the tension vector. At
a setting of 0, the imaginary line extends an equal distance
into and out of the keyframe, and the path through the
middle keyframe is curved. At 1.00, the Tension vector is
shortened to non-existence through KF2. At -1.00, the
effect is a lengthening of the Tension vector, causing the
path through the middle keyframe to be longer and
broader.
CONTINUITY — Determines the angle of the path into and
out of the keyframe. At 1.00, the effect is that of motion
dropping into and then out of the keyframe, similar to a
bouncing ball. At -1.00, the paths between the keyframes
become straight lines, accelerating through the keyframe.
BIAS — Determines whether the path will be “pulled”
towards the previous or the following keyframe. At 0, the
curve through the keyframe is gentle. At 1.00, the path is
pulled towards the previous keyframe. Entrance and exit
to the keyframe are on a straight line from the previous
keyframe, and the path of the effect travels completely
through KF2 before turning towards KF3. At -1.00, the
path is pulled towards the following keyframe. Entrance
and exit to the keyframe are a straight line pointed to the
following keyframe.
HOLD — Causes all parameters to hold at their starting values
throughout the keyframe duration. All changes occur at the
end of the keyframe duration, with no interpolation between
keyframes.
