I managed to get stuff working, here is my demo:
My server now spits out papervision compatible projection and object
matrixes, it took me more than two days to get to this result. And it's
definitely not 100% (x,y,z position is of when rotating), but it's
close, looks cool and good enough for now..
> I'm experimenting with augmented reality
> (http://www.hitl.washington.edu/artoolkit/), and I'm using my flash
> server (mammoth-project.org) to do the actual calculations. The server
> gives back matrix translations (per object) back to Flash. This works
> fine and very fast indeed, here is my proof:
> The projection matrix that artoolkit gives me is an OpenGL matrix in
> GL_MODELVIEW mode (right-handed). I believe I need to convert that to
> the left-handed papervision compatible coordinates.
> Who knows what the main differences between these coordinate systems are?
> And can someone confirm that this is the correct matrix papervision uses?
