Package georegression.struct.curve

Class ConicGeneral_F32

java.lang.Object

georegression.struct.curve.ConicGeneral_F32

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

EllipseQuadratic_F32

@Generated("georegression.struct.curve.ConicGeneral_F64")
public class ConicGeneral_F32
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.
