#Boxel Boxel is a near real-time pixelator and Minecraft codec.

##What does it do? Boxel pixelates and reduces the color pallete of images, websites and video at up to 24fps.

You can use it to make funky pixelated artwork from existing assets to display wherever you like. By default, Boxel creates a stream of PNG images along with JSON messages that describe the image.

Boxel was built to act as a codec for Minecraft. You can use the data it creates to build boxelized images, websites and video from blocks on a Minecraft server.

We've also created a client library that makes it easy to connect Bukkit compatible Minecraft plugins to a Boxel server.

##Demo app The best place to start with Boxel is probably the demo app.

It provides docker containers for Boxel and each of its dependencies (PhantomJS, Redis, Crossbar), as well as an example web front-end that will have a Boxel service running in just a few commands.

##Dependencies Boxel has three major dependencies:

• Crossbar: Used for device discovery, communication between the web application and the Minecraft server, and to serve the web application we built above.
• Redis: Used to push data into a PUB/SUB channel that Minecraft servers can subscribe to.
• PhantomJS: Used for headless browsing to capture images of websites.

####PhantomJS #####OS X Installing PhantomJS on OSX with Homebrew is simple:

$ brew install phantomjs

#####Linux Installing on Linux is unfortunately not as simple. Please refer to the official PhantomJS installation guidelines for instructions.

#####Running PhantomJS Once you've got PhantomJS installed, you will need to start it before running Boxel:

$ /usr/local/bin/phantomjs --webdriver=8910

If you plan to use a Docker image to install and run your Phantom instance, we highly recommend using this Docker image: wernight/phantomjs.

####Redis Next, Boxel requires Redis to send video data over PUB/SUB channels. Installation will vary depending on your system:

#####OS X On OS X, redis can be installed with Homebrew:

$ brew install redis

#####Ubuntu / Debian On a Debian-based system, redis can be installed with apt-get:

$ sudo apt-get install redis-server

On RHEL-based systems, the easiest way to get redis installed is to download the source tarball and perform a make-install:

$ wget http://download.redis.io/releases/redis-2.8.3.tar.gz
$ tar xzvf redis-2.8.3.tar.gz
$ cd redis-2.8.3
$ make && sudo make install

####Crossbar Finally, Boxel requires a WAMP router for service discovery. We use crossbar, which can be installed via pip:

pip install crossbar

##Installing Boxel After you've installed the dependencies listed above, install Boxel like any other Python package, with pip.

# using pip
pip install -e https://github.com/VerizonCraft/Boxel.git#egg=boxel

##Run it! Once the above dependencies are installed and running, you should be able to start the Boxel service like so:

# substitute the correct host/port for your redis server and crossbar router
boxel -W 50 -C palettes/5bit.yml video -R redis://localhost:6379/0 -U ws://localhost:8080/ws

##Usage See Boxel-client for code examples of video and website rendering in Minecraft.
