Method Details

getPoints

public Pnt2d[] getPoints(int n,
 double startAngle,
 double endAngle,
 double sigma)

Creates and returns an array of 2D points sampled on the circle associated with this CircleSampler. Random Gaussian noise (with standard deviation sigma) is added to the individual x/y coordinates.

Parameters:

n - number of points to sample

startAngle - initial angle (in radians)

endAngle - final angle (in radians)

sigma - sigma of Gaussian noise

Returns:

an array of sample points
