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.
