Class: Point

Point

Represents a 2d point.
Can be created in serveral ways:

new Point() [source] 

var point = new Point(1000, 1000);
var point = new Point([1000,1000]);
var point = new Point({x:1000, y:1000});

Methods

  • closeTo(p, delta) [source]

    • Compare with another point with a delta
    Parameter Type Description
    p Point
    delta Number
    Returns:
    Boolean:

  • mag() [source]

    • Return the magitude of this point: this is the Euclidean distance from the 0, 0 coordinate to this point's x and y coordinates.
    Returns:
    Number: magnitude

  • unit() [source]

    • Calculate this point but as a unit vector from 0, 0, meaning that the distance from the resulting point to the 0, 0 coordinate will be equal to 1 and the angle from the resulting point to the 0, 0 coordinate will be the same as before.
    Returns:
    Point: unit vector point

  • perp() [source]

    • Compute a perpendicular point, where the new y coordinate is the old x coordinate and the new x coordinate is the old y coordinate multiplied by -1
    Returns:
    Point: perpendicular point

  • angleWith(b) [source]

    • Get the angle between this point and another point, in radians from mapbox/point-geometry
    Parameter Type Description
    b Point the other point
    Returns:
    Number: angle

  • rotate(a) [source]

    • Rotate this point around the 0, 0 origin by an angle a, given in radians from mapbox/point-geometry
    Parameter Type Description
    a Number angle to rotate around, in radians
    Returns:
    Point: output point
