i’m fairly new to vvvv and, first of all, wanted to thank you for this nice project.
at the moment i have a little project going on where i’m stuck with ideas.
maybe you can give me some advice how to achieve my goal.
i got a wecam with a removed ir-filter. i covered it with lighting gels so almost none wavelengh other than ir-waves can pass.
in addition i got some tungsten fixtures, also covered with the gels.
the image looks good and promising.
the goal is the following setup:
So people can play with particles while seeing their shadows on the screen, captured by the ir cam.
now my patch includes the video-source in combination with “Frank’s” background-substraction shader which gives me a nice black and white layer/texture of my persons silhouette.
next i tried to use the contour plugin to generate point-coordinates of the silhouette. i tried to use these points with box2d’s EdgeChain.
But THAT doesnt seem to be the right way imo.
can you please point me in the right direction how to use my b&w texture to interact with particles or box2d shapes? can i convert the texture in a box2d shape?
thanks for your help
