Efficient way to set different 'tracking areas' on videoinput

vvvv beta general

hi!

now i select the areas by creating a 40x30 pixelmatrix with the pipette and a linear spreaded cross. then i set an iobox (buttons) with the same ‘aspect’. the rest is a lot of clicking.

i was wondering if there is a faster way (for me and the cpu) to do this? i need 3 sections like on a dart ‘disc’? with a bullseye.

cheers

use the Point2Vector node to get the angle and distance from the center of your matrix. then use the less, = and greater nodes, perhaps throw in a couple of ANDs and ORs
