how about some AR in haXe?

sorry for a bit of off-topic for FLARToolKit group, but it's pimping
friday, so check this out:

btw, does haxe have swc import now? can we bring FLARToolKit in?

nice work makc!
is it doing color tracking to find the blobs?
and are you determining which direction to point the resultant matrix based on a fixed triangle shape?  or can you use different triangles?

will download the source and dig later...

This is awesome! I wonder if there are other image recognition
techniques like hand gestures. Or facial expressions!

nah I dont think you can really do it from triangle shape. unless you
would run some kind of optimization algo to find the most orthogonal
matrix possible over 3D space of all possible Z-s for triangle
vertices, but I am not sure this will converge to any solution, not to
mention computing overhead.

the thing is you need at least 4 points. I learned about it in the
midway doing this thing, so I had to cheat and use blob sizes to
estimate Z-s. this didnt work well, and next iteration will have to
use more points.
