yeah, scons is Frementale is ancient, but building is still possible. Just add the line “from glob import glob as Glob” on top of “bin/SConscript” just like it is done in “./SConstruct”. I will add this patch in my next upload of the library…

Thanks for the response. I just got a chance to try to build the examples using scratchbox. It didn’t quite work. It seems like the version of scons in scratchbox is very old and not able to parse the ./SConstruct file (see below). How did you work around this?

the MADDE environment is still experimental and I have not tried it myself yet. But if you use scratchbox you can find an ARToolkitPlus package in extras-devel. For building the examples uncomment the last line in the ./SConstruct file.

Cool stuff. I was trying to build this myself using the new MADDE environment and got stuck because of lack of the scons tool. A tutorial on how to build the samples from ARToolkitPlus would be helpful.

I have to say this is quite impressive. I can actually see a use for this now as opposed to other AR demos I have seen.

This video really sparks my imagination. A few ideas you might want to think about: An Icon that represents a light source. Adding a filter to the rest of the screen, no reason you need to see the table, why not add grass over it? It may already do this, but support for various heights and orientations of objects in the scene.

Anyways, very cool.
