this isn’t even full size!
Many years ago, I wrote a processing sketch to take live video and generate a 3d pixel grid, varying the height of each 3d box based on the brightness of the video pixel it was sampling. And it was good. Times have changed, and so has processing. Now it’s easier to do what I was doing then in regards to accessing the video input and controlling the 3d camera in the sketch. There aren’t as many bells and whistles on this version as the original, but hey, it works today.
As such, you will need JMyron and Peasycam to run this sketch.
