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:
getReverseCurve in interface Curve2D
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 Curve2D
Specified by:
clip in interface OrientedCurve2D
Specified by:
clip in interface Shape2D
Parameters:
box - the clipping box
Returns:
the clipped shape
