Study of a water droplet
The colours of the facets are the normalized velocity vectors of the individual points.
Wait a while until the vibrations have calmed down, the gravitational force pushes the sphere on the floor into a hemisphere.
I am still working on adding several drops that will merge and/or move away from each other.
The menus are experimental and will change the velocity vectors.
Over the last few days, my attention has been focussed on the simulation of gases, liquids and ultimately material structures, which also follow the same laws (eulerian fluid simulation).
In other words, what would happen if you shot a handful of particles through a field of differently orientated vectors? How would the particles move and where would they end up at the end of their journey and what structures would they form?
Here is a basic example: demo
If you experiment a little with the parameters, you get interesting results. Many examples from nature came to mind when I was looking at this: traffic signs and vehicles following the signs, cloud formations, trees, fire, stars in the galaxy, organic structures like the iris of an eye or veins … if you rotate the vectors, vortices or circling currents form.
Here are a few more examples:
I can remember complex recursive functions to create a tree structure. This is no longer necessary. The entire tree structure is created in one go. To get hard lines, you just have to connect the previous points with the new points.
happy coding!

I am far away from being good in fluid simulation as FlipFluids

I stumbled over “open simplex noise” and found via coding train the way of Etienne Jacob … a big treasure of inspirations!
Since I am not allowed to spam the thread “Examples from Playground”…
Worth to highlight this demo nevertheless!
If you cut up the simple noise, you get a simulation of light reflections on a moving water surface

You freaky math wizard 
LOL! I believe (if true) this is only so that you do not make the rest of us look all too ridiculous 
. Don’t think any of us can compete with your pace and level of creative dev/thinking. 
Hi @roland, sorry for the broken link. The examples are all still there, just rearranged a bit. You can find them in the subdirectory tests
