Class EllipseRotated_F64

java.lang.Object

georegression.struct.shapes.EllipseRotated_F64

All Implemented Interfaces:

java.io.Serializable

public class EllipseRotated_F64
extends java.lang.Object
implements java.io.Serializable

An ellipse described using its center, semi-axes, and orientation.
(x'*cos(phi) + y'*sin(phi))^2/a^2 + (-x'*sin(phi) + y'*cos(phi))^2/b_2 = 1
x' = x-x_0, y' = y-y_0
where (x_0,y_0) is the center, (a,b) are major and minor axises, and phi is it's orientation.
