I'm having problems upgrading from ARToolkit version 2.65 to 2.71.2.
Everything in our program worked with the 2.65 version. After
incorporating the 2.71.2 version, it builds fine, brings in video fine,
etc. But it rarely recognizes the marker, and when it does, the blue
cube jumps erratically all over the screen at seemingly random places.
If I find the "sweet spot" (the only place in the camera's field of view
where it detects the marker at all), the cube draws at a random place
and orientation. If I don't find the sweet spot, no cube.
Any ideas?
