Curl

Curl is used to create curls or ringlets from the input fibres, the reference frame of this surface can be altered by specifying a new Up Vector value.

Inputs

Input	Type	Description
0	Data Flow	Fibres

Parameters

Parameter	Description
Curl	The amount of curl.
Curl Random	Used to randomize the curl on a per fibre basis.
Phase Random	Randomize the phase of the curl.
Root/Tip Curl	Control the amount of curl at the base/tip of the fibre.
Length	Controls the length of the actual curl, this can also be thought of as the phase of the curl.
Length Random	Randomize the length of the curl.
U/V Scale	The scale of the curl perpendicular to the fibre.
Maintain Length	If on, the curl will resample the fibre to ensure the length is maintained post evaluation but may shorten the appearance of the result.
Up Vector	The value for the up vector, by default this is the Y axis but can be a varying attribute to accommodate for issues where the surface normal is aligned with the Y axis.
