Ray2d Class

Ray with xy origin and direction

Methods

Name Description
ccwPerpendicularRay(result?: Ray2d): Ray2d Return a ray with cloned origin and with direction rotated 90 degrees counterclockwise  
cwPerpendicularRay(result?: Ray2d): Ray2d Return a ray with cloned origin and with direction rotated 90 degrees clockwise  
fractionToPoint(f: number, result?: Point2d): Point2d Compute and return origin plus scaled direction.  
intersectUnboundedLine(linePointA: Point2d, linePointB: Point2d): { cross: number, fraction: number, hasIntersection: boolean } Intersect this ray with the unbounded line defined by the given points.  
normalizeDirectionInPlace(defaultX: number1, defaultY: number0): boolean Normalize the direction vector in place.  
parallelRay(leftFraction: number, result?: Ray2d): Ray2d Return a parallel ray to the left of this ray.  
perpendicularProjectionFraction(point: Point2d): number Return the ray fraction where the given point projects onto the perpendicular ray.  
projectionFraction(point: Point2d): number Return the ray fraction where the given point projects onto the ray.  
set(origin: Point2d, direction: Vector2d): void Copy coordinates from origin and direction.  
createOriginAndDirection(origin: Point2d, direction: Vector2d, result?: Ray2d): Ray2d Static Create by copying coordinates from origin and direction.  
createOriginAndDirectionCapture(origin: Point2d, direction: Vector2d, result?: Ray2d): Ray2d Static Create from captured origin and direction.  
createOriginAndTarget(origin: Point2d, target: Point2d, result?: Ray2d): Ray2d Static Create from origin and target points.
