i´m facing a “performance problem” in vvvv and i just wanted to ask if anybody recently had the same problems or might even has a solution for it.
so here we go…
i´m currently building a multitouch wall using a IR camera, IR laser and a usual projector. hardware flow goes like this: finger touches glass -> finger interrupts laser beam -> IR camera -> cvv 1.2
everthing fine here. camera is around 30 fps and ccv detects blob and sends them via OSC to vvvv.patch flow goes like:get data from ccv (TUIO Decoder) -> get positions of blobs -> draw circle on projection
so far, the patch is very simple and it runs easily at 60fps. but here´s the problem. there is quite a big delay between sliding my fingers and the circles drawn. so the distance between the graphics and my finger is, depending how fast i move, pretty big.
so i would like to know if this issue is could be connected with the computer i use (which i dont think because camera is at 30fps and patch at 60fps), the setup of the installation or if anybody has experiences related to the ccv software and could give me some hints.
any advice would be helpful!
