Method Detail

getConicType

Conic2D.Type getConicType()

getConicCoefficients

double[] getConicCoefficients()

Returns the coefficient of the Cartesian representation of the conic. Cartesian equation has the form :

a*x^2 + b*x*y + c*y^2 + d*x + e*y + f

The length of the array is then of size 6.

getEccentricity

double getEccentricity()

Returns the eccentricity of the conic.

getReverseCurve

Conic2D getReverseCurve()

Description copied from interface: Boundary2D

Forces the subclasses to return an instance of Boundary2D.

Specified by:

getReverseCurve in interface Boundary2D

Specified by:

Specified by:

getReverseCurve in interface OrientedCurve2D

transform

Conic2D transform(AffineTransform2D trans)

Description copied from interface: Boundary2D

Forces the subclasses to return an instance of Boundary2D.

Specified by:

transform in interface Boundary2D

Specified by:

transform in interface Curve2D

Specified by:

transform in interface OrientedCurve2D

Specified by:

transform in interface Shape2D

Parameters:

trans - an affine transform

Returns:

the transformed shape

clip

CurveSet2D<? extends ContinuousOrientedCurve2D> clip(Box2D box)

Description copied from interface: Curve2D

When a curve is clipped, the result is a set of curves.

Specified by:

clip in interface Shape2D

Parameters:

box - the clipping box

Returns:

the clipped shape
