Here is what I'm looking for, I would like to animate a radar beam wich hit a surface. I've draw an arbitary 2D brown surface in the top of the canvas in a 250x250 pixel canvas. My radar is in the bottom middle and the beam will go from left to right and its few pixel wide. How can I change the pixel colors while the beam passes and restore the pixel color back. Is there any demo of such thing ?
