The dynamic program Newton has been rewritten in PHP. Originally, Newton was a C program that calculated the movement of the dbs and displayed the resulting positions on screen in real time. Real-time graphical output is not possible through standard web serving, so Imago Movens uses a different approach: the Newton calculation is performed on the server, and each calculated time step is rendered as an individual image frame. These frames are combined into an animated GIF and displayed after the calculation has finished.

The animation shows the calculated movement of the dbs through three-dimensional space as a two-dimensional projection. Depending on the selected parameters, the number of dbs, their movement, the size of the viewport, and their trails can be varied. What you see is therefore not a pre-made animation, but the visual result of a new Newton calculation performed by the server.
