# Example
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
|
||
|
|
var crosses = require("robust-segment-intersect")
|
||
|
|
|
||
|
|
var a0 = [-1, 0]
|
||
|
|
var a1 = [ 1, 0]
|
||
|
|
var b0 = [ 0,-1]
|
||
|
|
var b1 = [ 0, 1]
|
||
|
|
|
||
|
|
//Check if line segment a0, a1 crosses segment b0, b1
|
||
|
|
console.log(crosses(a0, a1, b0, b1))
|
||
|
|
```
|
||
|
|
|
||
|
|
# Install
|
||
|
|
|
||
|
|
```
|
||
|
|
npm install robust-segment-intersect
|
||
|
|
```
|
||
|
|
|
||
|
|
# API
|
||
|
|
|
||
|
|
#### `require("robust-segment-intersect")(a0, a1, b0, b1)`
|
||
|
|
Tests if the closed line segment `[a0,a1]` intersects the closed line segment `[b0,b1]`.
|
||
|
|
|
||
|
|
* `a0, a1` are the end points of the first line segment encoded as length 2 arrays
|
||
|
|
* `b0, b1` are the end points of the second line segment encoded again as length 2 arrays
|
||
|
|
|
||
|
|
**Returns** `true` if the linesegments intersect, false otherwise
