Markers on curved surfaces...?

In theory, one could make such a thing work (e.g., computer vision code 
to find curved markers), I suppose, but the ARToolkit cannot be made to 
do this.  It explicitly looks for squares, and throws out things that 
aren't square-like.

Dear all, I want to use artoolkit markers stuck to a curved surface. Has anyone done any work with this? Are there special transforms that might make the tracking work better? Rod.
