Constants

kDegrees2Radians → const double

Constant factor to convert and angle from degrees to radians.

kRadians2Degrees → const double

Constant factor to convert and angle from radians to degrees.

Functions

aangle(num x1, num y1, num x2, num y2) → double

angle(num x1, num y1, num x2, num y2) → double

assume p1(x1, y1) is the center, the angle of the line between p1 and p2 rotates from the vertical Y axis line of the coordinates

degrees(double radians) → double

Convert radians to degrees.

gaussianNoise(double mean, double standardDeviation, {Random? randomGenerator}) → double

gradualValue(num input, num target, {double power = 0.5}) → double

Input a value and a target, get a output between 0.0 and 1.0. The more the input is near the target, the more the output is near 1.0.

radians(double degrees) → double

Convert degrees to radians.

radiusToSigma(double radius) → double
