I'm trying to integrate latest code from artoolkitx 1.1.6 into the project. I'm still using Emscripten emsdk 3.1.7 and Opencv 4.5.0.
I think i have updated most of code changes (those of which we are more interested....) but still the 2d example doesn't show anything. It seems that it detect, quickly it get more then 50 matches, but it never goes ahead of this step, i'm not sure that is tracking.
Recently have tested the artoolkitx code both on Linux and Windows, and it can track very efficiently. Probably there is some code that still need a refactor.
One thing that i'm sure is that within this code i've never experiencing issue like webarkit/webarkit-testing#11 at least with the planarOrb2dTracker.
