F-CURVE MANAGER 1037
To move a tangent handle independently of its twin, ensure that Link Tangents
is disabled (Attribute manager) and Shift-drag the handle that you want to
move.
Flat
Horizontally aligns the tangents of the selected keys.
Function
Formula
The F-Curve produced by the formula sin(t*2*pi).
Using the Formula command, you can use math functions to create almost any shape of curve. The
Keys value denes the number of keys that will be created. The variable ‘trepresents time and may
have a value from 0 (the start of the sequence) to 1 (the end of the sequence). Angles must be entered
in radians.
You can use the following math functions:
ABS Absolute value LOG Logarithm
ACOS Arc cosine SIN Sine
ASIN Arc sine SINH Hyperbolic sine
ATAN Arc tangent SQR Square
COS Cosine SQRT Square root
COSH Hyperbolic cosine TAN Tangent
EXP Exponential function TANH Hyperbolic tangent
LOG10 Base 10 logarithm
Ramp Up, Ramp Down
Creates a curve that rises (Ramp Up) linearly from 0 to 100 over the length of the sequence, or a curve
that falls (Ramp Down) linearly from 100 to 0 over the length of the sequence.
