Methods

publicgetPoint

• getPoint(time: number): Vector

• Returns the point of intersection given the intersection time

  ---

  Parameters

  • time: number

  Returns Vector

publicintersect

• intersect(line: LineSegment): number

• Tests a whether this ray intersects with a line segment. Returns a number greater than or equal to 0 on success. This number indicates the mathematical intersection time.

  Parameters

  • line: LineSegment

    The line to test

  Returns number

publicintersectPoint

• intersectPoint(line: LineSegment): Vector

• Parameters

  • line: LineSegment

  Returns Vector
