Ray class

A ray defined by an origin point and a direction.

A ray starts at origin and extends infinitely in the direction of direction. Unlike Line, a ray has no endpoint.

Constructors

Ray(Point origin, Point direction)
const
Ray.fromAngle(Point origin, double deg)
Create a ray from an origin point and an angle in degrees
