Class Line

constructor

• new Line(p, v): Line

• Parameters

  • p: Point

  • v: Vector

  Returns Line

p

v

intersect

• intersect(l2): Optional<Point>

• Finds the point where two lines intersect returns none if the lines are parallel. *

  Parameters

  • l2: Line

    • Other line we want to check intersection with.

  Returns Optional<Point>

project

• project(p2): Point

• Finds what point on this line is closest to the input point.

  Parameters

  • p2: Point

    Point that we want to find closest point for.

  Returns Point

projectDistance

• projectDistance(p2): number

• Gives the minimum distance from p2 to the line.

  Parameters

  • p2: Point

    Point to get minimum distance for.

  Returns number

projectDistanceSquare

• projectDistanceSquare(p2): number

• Gives the minimum distance squared from p2 to the line. This function exists because it doesn't require any Math.sqrt, and is hence a more efficient way if one want to compare distances between many points.

  Parameters

  • p2: Point

    Point to get minimum distance for.

  Returns number

projectFactor

• projectFactor(p2): number

• Returns what number you would have to multiply the lines vector with to reach the point returned by project when starting from the line's point.

  Parameters

  • p2: Point

    Point whose projection we get the factor for.

  Returns number
