Fiducial Tracking

vvvv beta general
1

Hello,

I am in the process of building a patch using the Fiducial Tracker but I am having problems seperating the different XYZ information for each symbol. I have been reading into GetSlice and I have managed to seperate two symbol information but it seems the jerky (the outputs flicker between the two slices).

Is there anyone who will be able to help me get it up and running. What I want to do is link 5 symbols to 5 Video clips. So when user moves object it scales / moves the object. I will also then have same setup for 5 sound clips.

If anyone has had any luck with VVVV and Fidicuals please help - I am needing to get the project up and running by next weekend.

thanks in advance

hi darius , you can let the id that you want go through and avoid the others in diferent ways , here is an example ,

Thanks colorsound,

The patch you sent helps but my main problem is I want VVVV to set the Index number of the spread to the same number as the Fiducial. Therefore it will not matter about the order in which I place the symbols on the surface. So ID 0 will be 0 in the list of spreads and 1 = 1 etc.

thanks darius

i dont know if i understand your task, but maybe the former index output of the Sort node will help you…
