Using instanced animated geometry it is easy to create a simulation of cell based division;
There are two main methods that spring to mind to create this process. The first being to hand-keyframe the division process; animating visibility tracks and offsetting keyframed objects to reveal pre-constructed instances of a dividing cell. But that sounds too much like hard work, so lets look for an easier solution that we can automate. Particle Flow, with its Spawn test looks like a viable solution, however we immediately encounter an obstacle — the way cells actually divide. By looking at timelapse footage online of cells dividing, we can see that the nucleus of the cell divides, then the cell wall expands to accommodate the growth. This then pinches and closes, creating an identical copy of the original cell. Therefore, to create this method as realistically as possible, our main task is to simulate the growth and division of the cell.
