Sinus (Expression Function Reference)

The Function Profiles Sinus command in the expression editor inserts the token sinus(<period>,<amplitude>,[<offset>]) at the insertion point in the editing pane. This token generates a sinusoidal function with a wave-shaped profile. Replace the dummy arguments as follows:

<period>	Replace with an expression for the period, or wavelength, of the function from crest to crest, in frames.
<amplitude>	Replace with an expression from the maximum height of the function at a crest in SOFTIMAGE units.
[<offset>]	Replace with an horizontal offset for the function in frames. This expression is optional. If it is not included, the default offset is 0.

Example

sinus(50, 10, 12)

Generates a wave-shaped function that repeats every 50 frames, with a maximum value of 10, and which is 0 at frame 13 (1 + 12).
