A5.u.math.polartransform Method

Syntax

Arguments

anglenumber

The angle in degrees to move the point along.

distancenumber

The distance to move the point.

pointobjectarray

The point to transform. If no point is passed in then an x/y value of 0 will be used. Can be an array, or an object with properties "x" and "y".

Returns

pointobjectarray

The new location of the passed in point after transform.

Description

Perform a polar transform on a point.

Discussion

This method will transform a point along the given angle be a given distance. The point can be passed in as either an array where the first entry is the "x" value and the second entry is the "y", or and object with "x" and "y" properties. The resulting point will be in the same format (object or array) as in original point.

Example

var pnt = A5.u.math.polar.transform(15,20,[15,10]);
// pnt = [34.31851652578136, 15.176380902050415]
pnt = A5.u.math.polar.transform(15,20,{x: 15, y: 10});
// pnt = {x: 34.31851652578136, y: 15.176380902050415}
