Attention: Old PyARTK module is obsolete for a long time. Now the new ARTKBlender module is available. It works on current version of Blender and provides similar functionality as old one.
Blender 2.49 was released recently with new VideoTexture module derived from my blendVideoTex plug-in. It shows that plug-in is not needed anymore and I officially stopped its development.
I tried to run demo for PyARTK on new Blender, but it failed to detect markers. I spent several hours to find a source of this error and finally found it. It seems that VideoTexture module doesn’t provide correct video frame size after video replay was started. That’s why incorrect frame size was set to PyARTK and markers weren’t detected. So in this demo version is frame size hardcoded in script.
There is updated demo for download working on Blender 2.49.
For Blender 2.49a that uses Python 2.6 you’ll need new PyARTK binaries.
