    hi there,
    paying with tracking some video and want to read the output of argh value of the part of video i want to track.
    trying to use suckah, but can't seem to get floating values to output properly. I seem to just get the same three numbers 0.004 outputting no matter where I click.
    Any ideas why and how to fix greatly appreciated
    thanks

      check this thread: https://cycling74.com/forums/colour-tracking-with-a-webcam-in-jitter
      also, I think it should be a $f1 instead of a $i1 in your vexpr object...

      thanks for that, great.
      i'm also trying to read the placement of any red (or any colour actually) the camera picks up, and outputting all those positions - just like the tracking, but able to track multiple positions - i.e if theres a blob of red top left, middle of screen, and bottom right I would get separate readings of the x-y value of each of those points.
      Like using jitspill - but able to get the x & y values of each plane in a way that I can place it onto a table, or something similar to generate tones or control a filter on a noise generator etc...
      the concept is to have a bunch of red balloons, or cards in a space. These control the sound by producing tones, or manipulating the filter etc...
      any ideas/direction/help greatly appreciated
