comp-geo v0.0.10

This module is forked from Citybound Comp-Geo, repaired and made partially working by @mflux.

comp-geo

2D Computational Geometry for Javascript

Uses primitives with a configurable thickness for giving reasonable results even for inaccurate inputs.

Status of this module

The module this was forked from was no longer being maintained. I've managed to get skeleton and shape / paths working. The rest may still be broken as the tests are not currently passing. Use at your own peril!

@mflux

Tests

npm install npm run test

Development and Web Example

npm install npm install -g budo npm run dev

Primitives

• Line, Ray, LineSegment
• Circle, Curve

Shapes

• Path (LineSegments + Curves)
• Shape
• Stroke

Shape Operations

• Clipping/Boolean Operations
• Offsetting/Straight Skeleton

Skeleton Triangulation

See example/app.js

For general use from path to THREE.js roof shapes:

//  Path is an array of LineSegment(s)
const skeleton = new CompGeo.Skeleton( path, Infinity );
const skeletonPath = new CompGeo.shapes.Path( skeleton.spokes );
const shape = new CompGeo.shapes.Shape( path.concat( skeletonPath ) );
const geometry = shape.triangulate();
