Tracking light objets. Help!
Hi all,
i’m trying to sense with a webcam of a laser light movement on a wall
i’m using the [jit.findbounds] object for tracking light
Someone know of better objets (or external, etc.) to solve it?
Thank you very much!

Hi laserpilot,
Thank you! Very interesting patch! i’m studing a lot.
A question relating to the object: [jit.op @op >= >= >= >= @val 0.]
What are the differences between to use 4 equal operators (multi op) , or to use only one?
[jit.op @op >= >= >= >= @val 0.] or [jit.op @op >= @val 0.]
for me, the result would be the same in both cases
Thank again!

I forget my original reasoning for that since that project is a couple years old now. I think it was just reassuring me that I’m doing it for all of the color channels ARGB. In other cases you would use 4 different operators to do different things on the color channels, but in this case since they’re all the same it doesn’t really matter.
