Constructor Detail

Ray2D

public Ray2D(double x1,
             double y1,
             double x2,
             double y2)

Two-point-coordinate constructor. The direction is relative to the origin. The ray goes through both points.

Parameters:

x1 - x-coordinate of origin

y1 - y-coordinate of origin

x2 - x-coordinate of direction

y2 - y-coordinate of direction

Method Detail

render

public Line2D render(double distance)

Render the ray as a scaled line.

Parameters:

distance - scaling factor to render the line

Returns:

a line simulating an infinite ray
