planar-graph-to-polyline
|
|
========================
|
|
Converts a planar graph to a collection of nested polylines (as would be consumed in a GeoJSON/TopoJSON file for example).
|
|
|
|
# Example
|
|
|
|
```javascript
|
|
var graphToPolygons = require("planar-graph-to-polyline")
|
|
|
|
var edges = []
|
|
var positions = []
|
|
|
|
for(var i=1; i<=3; ++i) {
|
|
var v0 = positions.length
|
|
for(var j=0; j<10; ++j) {
|
|
var theta = 2.0 * Math.PI * j / 10
|
|
positions.push([ i * Math.cos(theta), i * Math.sin(theta) ])
|
|
edges.push([ v0+j, v0+((j+1)%10) ])
|
|
}
|
|
}
|
|
|
|
console.log(graphToPolygons(edges, positions))
|
|
```
|
|
|
|
Output:
|
|
|
|
```javascript
|
|
[ [ [ 20, 29, 28, 27, 26, 25, 24, 23, 22, 21 ],
|
|
[ 11, 12, 13, 14, 15, 16, 17, 18, 19, 10 ] ],
|
|
[ [ 0, 9, 8, 7, 6, 5, 4, 3, 2, 1 ] ] ]
|
|
```
|
|
|
|
# Install

|
|
```
|
|
npm install planar-graph-to-polyline
|
|
```

# API
|
|
|
|
#### `require("planar-graph-to-polyline")(edges, positions)`
|
|
Converts a planar graph into a collection of nested polylines
|
|
|
|
* `edges` are the edges of the graph
|
|
* `positions` are the locations of the vertices in the plane
|
|
|
|
**Returns** A list of loops encoding the regions bounded by the graph
