It would be interesting to see where certain lines come from, like the horizontal ‘waves’ on the shirt of which nothing in your picture is visible.
ok, what’s happening here is I run a particle across the screen. it looks at the pixel it is on. the red value determines the direction of the force: 0 – 360. The blue value determines the magnitude of the force. The force gets added to the pixel’s velocity. White is 0 degrees at maximum force, so you get horizontal lines.
