Hi,

I'm trying to use ARToolkit with Coin, but I have a problem setting the
right view. I've tried reading to ARToolkit sources (2.61), but the lack
comments makes it very hard to understand. Can someone give me a hint?

Thanks, Murad

Hi Murad,

Integrating ARToolkit into a scene graph is an interesting problem because
it uses its own coordinate system in camera coordinates which is not
necessarily orthogonal like your scene graph and projection matrices are
expecting. We integrated marker tracking into our scene graph software, and
we described it in a poster which we presented at the ART02 workshop last
year:

You might want to check this out which describes how to fix up some of the
problems and integrate into a scene graph.

regards,
Wayne
