LightPainting

Hello all,

I tried to code a LightPainting sketch for educational use. I don't need a superb result but something basic and, if possible, fun.

My current code display some "splash" during the record. It's very ugly but I don't know how to reduce this.

Here is a example of what I called "splash" :



And here is the code :

1. cam.loadPixels();
2. screen.loadPixels();
3. for (int i = 0; i < cam.pixels.length; i++) {
4.       if ((brightness(cam.pixels[i]) > brightLimit) && (brightness(cam.pixels[i]) > brightness(screen.pixels[i]))) {
5.             screen.pixels[i] = cam.pixels[i];
6.       }
7. }
   

Entire code is on GitHub if you want to help a newbie.

Thanks for your help.
