Method Details

approxCubicBezier

public static List<BiArc> approxCubicBezier(CubicCurve2D.Double bezier,
 int nrPointsToCheck,
 double tolerance)

Algorithm to approximate a bezier curve with bi-arcs.

Parameters:

bezier - The bezier curve to be approximated.

nrPointsToCheck - The number of points used for calculating the approximation error

tolerance - The approximation is accepted if the maximum deviation at the sampling points is smaller than this number.

Returns:

the approximated biarcs

computeIncenterPoint

Parameters:

a - point A of the triangle

b - point B of the triangle

c - point C of the triangle

Returns:

the incenter point G
