This post is not very interesting, but I was playing a little bit with Daemons and Grids and get this paint fiber look.
I got this fluid using a grid and a D_Spline daemon, nothing special! It was rendered with Mental ray RFRK Mesher.
These days I was looking for information about whirlpools. Here some links:
I found some threads in the forums and was playing arround this subject. By now I have not great results but think it is quite easy to get interesting results using vortex and DSplines daemons.
First test I did was with partcle base fluids, the problem is you need a lot of particles.
These are some tests using HYBRIDO where you can generate a lot of particles, in this tests I have used few cells so they are not showing a lot. In the first example I used a simple vortex, the other three a DSpline gives you more control and let you play with several configurations, animating parameters and its layers. Now I am working on the other layers of the simulation, splashes , spray, foam, etc.
Some test scenes.
This week I made a very big and newbie error in a set up scene, the grid domain is too big. Next pictures show the difference between adjusting the GD to the full scene and only to the simulation volume.
Always try to adjust the GD to the simulation volume and you will get a better simulation performance, in this case I get double number of particles, with less number of cells and more frames simulated and approximately using same time for the calculation (Simulated in a quad-core).
