idris-line-intersect

Takes two lines and returns all intersection points or false if there are none

Install

$ npm install idris-lineintersect

Usage

var il = require('idris-line-intersect')

with coordinates

.coordinates( line1, line2, callback )

var line1 = [[0,0],[8,3],[1,6],[9,9]]
var line2 = [[2,2],[6,1],[6,9]]

il.coordinates(line1, line2, function(points) {
    // returns an array of points
    console.log(point)
})

Log looks like this

[ 
    [ 4, 1.5 ],
    [ 6, 2.25 ],
    [ 6, 3.857142857142857 ],
    [ 6, 7.875 ] 
]

with features

.features( lineFeature1, lineFeature2, callback )

var lineFeat1 = {
    type: 'Feature', 
    geometry: {
        type: 'LineString', 
        coordinates: [[0,0],[8,3],[1,6],[9,9]] 
    }
}
var lineFeat2 = {
    type: 'Feature', 
    geometry: {
        type: 'LineString', 
        coordinates: [[2,2],[6,1],[6,9]] 
    }
}

il.features(lineFeat1, lineFeat2, function(points) {
    // returns an array of point features
    console.log(point)
})

Log looks like this

[ 
    { type: 'Feature',
    properties: {},
    geometry: { type: 'Point', coordinates: [ 4, 1.5 ] },
    { type: 'Feature',
    properties: {},
    geometry: { type: 'Point', coordinates: [ 6, 2.25 ] },
    { type: 'Feature',
    properties: {},
    geometry: { type: 'Point', coordinates: [ 6, 3.857142857142857 ] },
    { type: 'Feature',
    properties: {},
    geometry: { type: 'Point', coordinates: [ 6, 7.875 ] }
