Hello everyone,i set up the set for detect the point with Diffused Illumination.when i use touchlib example ,the effect is ok .
but when i use freeframe(coutour) to do the same work in vvvv,the odiverflow is so much(i have adusted the threshold to the biggest).
i felt the effect of touchlib is better.
so i want to ues freeframe write a plus which move all functions of touchlib to it .
can somebody who have done that give me some suggestion?
thanks advance!

Not entirely sure what you’re looking for, but some points:

1. You will not get touchlib to natively run alongside freeframe code *unless* you program things in C++, but I’m also not sure how that helps you.

2. There are tons of examples of using VVVV with OSC http://www.google.com/search?q=vvvv+osc ... and touchlib can send OSC messages standardized by the TUIO dialect.

3. I would recommend if you like the feel of touchlib’s touch support better than something that is native in VVVV, i would investigate #2, and have VVVV + FreeFrame just respond via the OSC protocol to TUIO formatted messages… and that should work and be less headache.

However, I’m not a VVVV programmer, so I’m not sure, but by googling all of this, that’s what I’d offer.

@th0m: Thats the thing vvvv currently supports reading from OSC but doesnt support TUIO syntax… so pretty much if you want to use vvvv like i do, you have to make your own specific method of reading TUIO there might be a patch like that available but i haven’t found it, but in my defense i haven’t been looking around for it.

If in your problem you are refering to the shadow of your hand in touchlib decrease, your brightness, and increase your rectify sliders.... till only you have your inputs being detected and there is no shadow.
In vvvv in your videoIn block click on the properties pin and decrease the brightness and increase your contrast… on the contour block, enable cleanse, and show contour, next adjust the threshold so that only your inputs get detected.

gaoxu, your image looks like that in touchlib because you are using filters for FTIR, not DI. You need to use the DI filters and add in simplehighpass and scalerto your config.xml and take out brightnesscontrast.
