Divide a space in grid?


    Sep 15 2012 | 8:22 am
    I am taking the video feed from a Kinect and need to track if the right hand is in a certain quadrant. basically, I am dividing the space in 8 equal squares. If the hand is in that space then it triggers an event in Max. In the past I have done something alike using if-then statements but I believe that it is not the best way and there must be something better. Anyone has an idea?

      Nice! Thank you. I will work a bit with this.

      You can also do it with a scale object (and change to not re-bang within the same section/number)

      well i also tried it with a scale object , but it gives different results....

      Interesting that it's so different. It's the +1 that's the difference I guess. It comes down to how you want to space it as in yours the "8" isn't a section of the slider. It's the tippy top of the slider. That's probably the best mapping if you're mapping it to something, but maybe not ideal if you want 8 equal slices.

      Actually, I have 2 columns of 4 squares each. I will duplicate the patch, one for the x values, one for the Y-values and then match the bangs. And off course test what results are the mmost accurate.

      Almost there. I pack the X and Y values in a list and match them. The only problem I have is that I am not getting a bang if the Y value changes but the X stays the same. What should I do for that? When I simply send a bang to the pack object, there are sometimes two matches instead of one.

      use pak instead of pack

      Pak is nice but I sometimes get two or even three bangs where there should only be one bang. What am I doing wrong?

      Sorry to reply to my own post but I found the problem is with the match object. I am feeding it a list but the object takes the list as a sequence so if you send and then < 1 2> it will see and then when you send he will match the but also the interpolated < 1 1>. Now, is there a way to get around this?
