public createPoint(origin: javafx.geometry.Point2D, angle: Number, radius: Number) : javafx.geometry.Point2D

This function creates a new Point2D from given polar-coordinates.

This function creates a new Point2D from given polar-coordinates. The new Point2D is created from polar-coordinates (angle, radius) using a given Point2D as origin.

Parameters

origin

The origin to start calculation from.

angle

The angle of the polar-coordinates.

radius

The radius of the polar-coordinates.

Returns

Point2D

The created Point2D .

Calculates the squared distance between two Point2D objects.

Calculates the squared distance between two Point2D objects.

Parameters

p1

The first Point2D.

p2

The second Point2D.

Returns

Number
