code from day 6 (vector field) is here: day6

pc users, you will need the vector math addon for the first 3 examples. the last one requires ofxVectorMath + ofxOpenCv.  You’ll likely find it easiest to copy the allAddons example codeblocks project and use that with the src code of this example.  (since the allAddons example has every addon included properly).

have fun !!
