The ongoing lack of tutorials is still one of the most pressing issues to resolve for me & everyone else using (or trying to use) these libraries. Add to this the recent lack of updates to this blog, it all might give the illusion the project itself is stagnating. This couldn’t be further from the truth. In fact, the past few months have seen an incredible uptake of interest as well as development effort (93 revisions since beginning of the year), but I’m also close to reaching the point where I’ll impose a temporary new feature freeze as soon as version 0021 has been released within the next 6 weeks. 0022 will most likely be far more focused on a new, much improved system for documentation and a new website…
In the meanwhile, I’ve been doing my best to respond to concrete issues & tasks people were trying solve on the Processing forums as well as the issue tracker. The list of demos on OpenProcessing has grown too. And thanks to personal heroes of mine, like Golan Levin, Daniel Shiffman and their students, there’re also a number of very interesting student projects this year, which are utilising the libraries and (in some cases) have their code explorations shared (like good citizens tend to do :). A round-up post of these will follow shortly.
Speaking of missing examples and small projects, teaching workshops has been another well under-documented effort of mine. For most of them, I’ve created a Mercurial repository on this website and I’d encourage you to download and play with these examples as well. A lot of them are more advanced than the examples bundled with each release, some utilize 3rd party libraries and all are generally full of comments, not just about library specific topics. Please also send your virtual thanks to all the unis & institutions allowing this material to be shared!

Before I get to the compiled list of mini-tutorials and discussions from the Processing forum, Amnon Owed has recently produced two excellent tutorials for this project and I sincerely hope his efforts will inspire other users to follow suit:
List of recent forum threads (including lots of source code), sorted by subject:
Interaction, events, multi-threading
How to use the Toxiclibs Voronoi class?
2D Collision detection – irregular shapes (computer vision blobs)
PerlinNoise to specified target destination
What does Vec2D.heading() in Toxiclibs do exactly?
How to calculate the tangent line of a circle?
Mouse within a certain area
using toxiclibs geomutils to solve the “pulley problem”
Geo location (Twitter & Flickr)
These two threads are about JAXB, which is indirectly referenced by various toxiclibs geometry types in order to store them as XML. In anyway, many users are interested in data visualization and JAXB is lightyears ahead of the default XML library bundled with Processing…
Last, but not least: If you have any similar questions, interest in running workshops at your university/company or any small tutorials to share, please do get in touch! ¡Muchas gracias!
