in and slow out”). In freeform animation on page 7792 of a biped, you can use
them to change the timing of a limb's movement from key to key.
The TCB controls are in the TCB section of the Key Info rollout on page 4288
.
TCB (Tension, Continuity, Bias)
The TCB Position controller provides Tension, Continuity, and Bias controls
of the splines of a function curve.
TCB Controllers on page 3183 also produce curve-based animation much like
the
Bezier controllers on page 3063 . However, TCB controllers do not use
tangent types or adjustable tangent handles. They use numeric values to adjust
the Tension, Continuity, and Bias of the animation.
Tension Controls the amount of curvature in the animation curve.
High Tension produces a linear curve. It also has a slight Ease To and Ease
From effect.
Low Tension produces a very wide, rounded curve. It also has a slight negative
Ease To and Ease From effect.
The default value of 25 produces an even amount of curvature through the
key.
Continuity Controls the tangential property of the curve at the key. The
default setting is the only value that produces a smooth animation curve
through the key. All other values produce a discontinuity in the animation
curve causing an abrupt change in the animation.
High Continuity values create curved overshoot on both sides of the key. Low
Continuity values create a linear animation curve.
Low continuity creates a linear curve similar to high tension except without
the Ease To and Ease From side effect.
The default value of 25 creates a smooth continuous curve at the key.
Bias Controls where the animation curve occurs with respect to the key.
High Bias pushes the curve beyond the key. This produces a linear curve
coming into the key and an exaggerated curve leaving the key.
Low Bias pulls the curve before the key. This produces an exaggerated curve
coming into the key and a linear curve leaving the key.
The default value of 25 distributes the curve evenly to both sides of the key.
