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
