Method Detail

getSupportingLine

StraightLine2D getSupportingLine()

getHorizontalAngle

double getHorizontalAngle()

Gets Angle with axis (O,i), counted counter-clockwise. Result is given between 0 and 2*pi.

getOrigin

Point2D getOrigin()

Returns a point in the linear shape.

Returns:

a point in the linear shape.

getVector

Vector2D getVector()

Return one direction vector of the linear shape.

Returns:

a direction vector

getIntersection

Point2D getIntersection(LinearShape2D line)

Returns the unique intersection with a linear shape. If the intersection doesn't exist (parallel lines), returns null.

transform

LinearShape2D transform(AffineTransform2D trans)

Description copied from interface: Shape2D

Transforms the shape by an affine transform. Subclasses may override the type of returned shape.

Specified by:

transform in interface Curve2D

Specified by:

transform in interface Shape2D

Parameters:

trans - an affine transform

Returns:

the transformed shape
