Package Exports
- poly-parse
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (poly-parse) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
poly-parse
Parses a .poly file from Triangle and returns a JSON.
A .poly file represents a PSLG, as well as some additional information. PSLG stands for Planar Straight Line Graph, a term familiar to computational geometers. By definition, a PSLG is just a list of vertices and segments. A .poly file can also contain information about holes and concavities, as well as regional attributes and constraints on the areas of triangles.
The text file is parsed with Papa Parse.
Install
npm install poly-parseExample
const polyparse = require('poly-parse');
polyparse('./A.poly', { download: true })
.then(data => console.log(data))
.catch(err => console.log(err))Returns a Promise with the parsed object.
