In this tour we are going to show one method to create an artful animation by applying simple rules of physics and addapt them to our wishes. The videos in this tour were all recorded from realtime OpenGL animations of ours.
Let's have a look at the first video.
Colors fly across the canvas and create a dynamic picture.
But what's happening here? The following video explains it.
From the moving red button a force acts on the particles. It pushes away red particels and attracts blue particles. The blue button at the center of the canvas pushes away blue particels and attracts red ones. An interesting dance between the different forces results. The first video was produced the exact same way, just with a specifically designed blending mode.
Let's add some exaggerated relativistic correction now. This way we can observe patterns that usually only are visible on a very large scale in space and time.
Now we have seen, that we can obtain really interesting results by simulating physical systems with unusual parameters. By playing with parameters like friction or opacity we can also achieve even more abstract results, which appear to have nothing in common with the original system. You can watch an example in the following video, which is also a derivation of the previous animations.
To complete our tour, let's have a look at another physical system. An algorithm, that was inteded to simulate the observation of atoms in an electron microscope creates this colorful feast after some modifications.
