offsetSymmetric method

double offsetSymmetric(
  1. double x, [
  2. double roughnessGain = 1
])

Generates a random offset between -x and x based on roughness.

This is a convenience method for symmetric offsets.

Implementation

double offsetSymmetric(double x, [double roughnessGain = 1]) {
  return offset(-x, x, roughnessGain);
}
