EllipseImplicitEquation

Represents the implicit equation of an ellipse.

Constructors

EllipseImplicitEquation

public EllipseImplicitEquation(float x, float y, float angle, float radiusX, float radiusY)

Construct a new rotated ellipse equation.

Parameters:

x (float)	Centre x.
y (float)	Centre y.
angle (float)	Angle of main axis.
radiusX (float)	Radius along the world x-axis.
radiusY (float)	Radius along the world y-axis.

EllipseImplicitEquation

public EllipseImplicitEquation(float x, float y, float radiusX, float radiusY)

Construct a new axis-aligned ellipse equation.

Parameters:

x (float)	Centre x.
y (float)	Centre y.
radiusX (float)	Radius along the world x-axis.
radiusY (float)	Radius along the world y-axis.

Methods

Evaluate

public float Evaluate(float x, float y)

Evaluate a coordinate pair. Zero scalar reside on the ellipse, negative values are inside the ellipse. The centre of the ellipse is associated with the most negative value of -(radiusx * radiusy).

Parameters:

x (float)	X coordinate.
y (float)	Y coordinate.

Returns: Scalar according to circle equation.

ToString

public override string ToString()

Returns the fully qualified type name of this instance.

Returns: A String containing a fully qualified type name.

Overrides: ValueType.ToString
