One of the things that interests me most about Ember, is the fact that the input files are a stack of PNGs. This means that one can essentially feed the printer images without the need for solid body modelling, STLs or slicing! It's a pretty cool side to the machine and one that can be explored using Processing.

Processing is a Java based, open source programming language that uses a graphical programming model, allowing the user an easy way to quickly create images.This Instructable will take you through my first foray into using Processing, from drawing a simple image to creating a stack of PNGs to mimic hair and then printing them on Ember. It's quite an easy language to get into if you have any prior programming experience and there are lots of resources online to help you muddle through those first few sketches!

Note: this Instructable will all be from the perspective of using a Mac.

Step 1: Download and Install Processing

First off, you'll need to download and install Processing. Processing is available for Mac, Windows and Linux; it can be found here.

Once downloaded, unzip the contents and copy across the Processing icon into your location of choice. Double click on the icon and you'll open up your first sketch.

If you've ever written Arduino code, the integrated development environment (IDE), will look instantly recognisable!

Next we talk about how to structure your code and a quick example

<p>Nice helpful intro to Processing!</p>
<p>This needs an animated gif.</p>
<p>Can't wait to give this a go!</p>
