This images features two repelling fixed points and an attracting saddle point. Other picures Quite big dots show the effect of smearing ink on paper. A simple underlying flow from the left to the right was chosen to make the fading of the droplet tails visible. We are dealing with semi transparent ink here, so if the ink concentration on the paper becomes less, the background shines through. Rather small dots were chosen here to create a rudimentary overview impression of the underlying circular field The absorbtion factor for this kind of paper was set to a very small value, so the ink droplets produce longer tails, when they get smeared by the flow, with features a saddle point in this case.
Bigger dots illustrate the stochastic influence used in the Virtual Ink Droplet Method.
This sheet of paper was inintially densly scattered with a lot of very small dots, resulting in a LIC like image. This rather artificial dynamical system features a spiral system, where dots not belonging to the spiral keep untouched. Here is an MPEG video too.
