ofxClipper2

An openFrameworks addon wrapping Clipper2, a library for polygon clipping, offsetting, and triangulation.

Installation

Clone this addon into your addons folder with submodules:

git clone --recursive https://github.com/YOUR_USER/ofxClipper2.git

If you already cloned without submodules:

cd ofxClipper2
git submodule update --init --recursive

Requirements

• openFrameworks 0.12+ (C++17)
• Clipper2 is vendored as a git submodule under libs/Clipper2

Usage

Include the wrapper header to get both Clipper2 and openFrameworks conversion helpers:

#include "ofxClipper2.h"

using namespace ofxClipper2;

PathsD subject, clip;
subject.push_back(MakePathD({ 100, 100, 200, 100, 200, 200, 100, 200 }));
clip.push_back(MakePathD({ 150, 50, 250, 150, 150, 250, 50, 150 }));

PathsD result = booleanOp(ClipBooleanOp::Intersection, subject, clip);
drawPathsD(result);

You can also use the Clipper2 API directly via Clipper2Lib types and functions.
