ConicGeneral_F64

java.lang.Object

georegression.struct.curve.ConicGeneral_F64

All Implemented Interfaces:: Serializable

Direct Known Subclasses:: EllipseQuadratic_F64

public class ConicGeneral_F64 extends Object implements Serializable

A*x² + B*x*y + C*y² + D*x + E*y + F=0

All coefficients are real numbers and A,B,C are all not zero. The discriminant is defined as B² - 4*A*C.

Ellipse: B² - 4*A*C < 0

Parabola: B² - 4*A*C = 0

Hyperbola: B² - 4*A*C > 0

NOTE: these parameters are unique only up to a scale factor.
