(static) makeVectorFeatures(point) → {object}

Source:

tools/geometry/src/2DVector.js, line 43

Since:

0.1.0

Calculates length and versor of a vector

Example

> makeVectorFeatures({x: 1, y: 1})
{
	length: 1.4142135623730951,
	versor: {x: 0.7071067811865475, y: 0.7071067811865475}
}
> makeVectorFeatures({x: 0, y: 0})
{
	length: 0,
	versor: {x: 0, y: 0}
}

Parameters:

Name	Type	Description
`point`	object	A point representing a vector starting in the origin

Returns:

The vector features: {length, versor}

Type: object
