# pb_CSG

A C# port of [CSG.js](http://evanw.github.io/csg.js/) by Evan W for use in the Unity game engine.

## Install

To install, simply check out this repository in the `My Project/Packages` directory.

```

cd My\ Project/Packages

git clone https://github.com/karl-/pb_CSG.git co.parabox.csg

```

## Quick Start

pb_CSG provides an interface in the `CSG` class for creating new meshes from boolean operations.  Each function (`Union`, `Subtract`, `Intersect`) accepts 2 gameObjects: the left and right side.  A new mesh is returned.

Example use:

	// Include the library

	using Parabox.CSG;

	...

	// Initialize two new meshes in the scene

	GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube);

	GameObject sphere = GameObject.CreatePrimitive(PrimitiveType.Sphere);

	sphere.transform.localScale = Vector3.one * 1.3f;

	// Perform boolean operation

	Model result = CSG.Subtract(cube, sphere);

	// Create a gameObject to render the result

	var composite = new GameObject();

	composite.AddComponent().sharedMesh = result.mesh;

	composite.AddComponent().sharedMaterials = result.materials.ToArray();

Result:
