Class FlatAlignment

java.lang.Object

org.monospark.geometrix.GeometrixObject

org.monospark.geometrix.shape.flat.alignment.Alignment<Two>

org.monospark.geometrix.shape.flat.alignment.FlatAlignment

public final class FlatAlignment
extends Alignment<Two>

A two-dimensional alignment which can translate and rotate the polygon model. When aligning a shape, the rotation is applied before the translation.

Field Detail

NO_ALIGNMENT

public static final FlatAlignment NO_ALIGNMENT

This alignment has no translation and rotation.

Constructor Detail

FlatAlignment

public FlatAlignment(Vec<Two> translation,
                     double rotation)

Creates a new FlatAlignment object from a translation vector and a rotation value.

Parameters:

translation - a vector by which the shape will be moved

rotation - a value which specifies the clockwise rotation in degrees of the shape

Throws:

java.lang.NullPointerException - if translation is null

java.lang.IllegalArgumentException - if rotation is equal to (+/-)Infinity or NaN

Method Detail

getLocalPoint

public Vec<Two> getLocalPoint(Vec<Two> point)

Description copied from class: Alignment

Transforms a point in the global coordinate system into a point in the local coordinate system of this alignment.

Specified by:

getLocalPoint in class Alignment<Two>

Parameters:

point - the two-dimensional point which should be transformed

Returns:

a two-dimensional point, which equals the global point in the local coordinate system.

getGlobalPoint
