Nothing really new to show (still the same visualisations as the previous post, it’s just a test app) but right now, we have :

- Check if APIKey is valid
- Choose file to analyze
- Checks MD5 hash, if it already exists on the EchoNest servers, you can retrieve datas
- If MD5 don’t exist, uploads the MP3, wait for the analysis to complete, then tells you it’s ready

- Every EchoNest API track methods are done, may have to refine a bit the data that’s sent back to the caller object

- Everything is loaded asynchronously (is this even the right term ?), so app won’t hang up during track upload or segments download
- We also have track and artist search by string

# TODO
- EchoNest API artist methods, hottness, and stuff
- Maybe find a better way to notify caller object (right now I’m using NSNotification, works, but could be better)

Anybody wants to try ? Tell me and I’ll send you sources. The stuff is still not ready for a full release but you can still do some nice stuff. I started putting all those datas in an NSOpenGLView, if you know what I mean ^^

Working on it… ^^

I had some time today, and I wondered how to code Arduino sketches using XCode.

So I made a template. You can download it here : http://www.sendspace.com/file/ebij84

Hey there

Lately, I’ve been working a lot with Augmented Reality using the ARToolKit SDK. It’s really a cool stuff.
So when I saw an email from ARToolWorks saying that it was possible to test a pre-release of the ARToolKit SDK for iPhone, well, I had to.

I did not do a lot besides what’s in the example XCode project bundled with the SDK, but maybe you’d like to see ^^

By the way, the skull model was made by Pierre Vanni.

Sorry for the crappy quality of the video

So, last week-end at a flea market, I got a Sport-Elec 4, one of those late night shopping “muscle maker”, for 2 euros. It works, so I opened it ^^

For the past few days, I’ve been playing with ARToolKit and frankly, it’s great.

Maybe you already saw the work I done in linking my Arduino to 3D Studio Max. As soon as I got multi tracker AR working, I thought “damn, I have to try to build a tool to do some modelling the same way you model clay”.

I’m pretty bad at all that C++ stuff, so my code is just a patchwork of fragments taken from different sources, but it works for a prototype.

I’ve spent the morning playing with ARToolKit and the port for processing NyARToolKit and I was struggling with the lighting conditions. After going through all the hoops of calibrating my camera, etc…, I was wondering how you could use Augmented Reality in the dark. So I took my good old 8×8 matrix pseudo shield, wrote 2/3 additional lines of code to my do-everything sketch, and I had a nice little “marker” made of light.
