Cellular morphogenesis

[jojorealflow]

hello to all. I'm starting having fun with realflow. I have to say that is a very very powerful software. My filed of work is mainly biomedical and so I've tried to create some recipe for morphogenesis and cellular growing withouth too much success. What I had in mind was something like this (figure 6)

because no matter how try you hard with displacement and modelling/whatever, nature is always better at creating cells. Something very interesting can be also read here http://ajplung.physiology.org/content/290/4/L777
Probably it's a challenge but it will be for sure something unseed in gfx if we exclude some pioneering works cited (and of course a reference to morphogenesis by Turing is mandatory
Hope someone has some advice/recipe to share.
Thanks in advance for everyone that would like to reply

Hi Giorgio,

DLA (diffusion limited aggregation) is not really new in CGI/VFX. There's a Houdini-based approach, for example, but the most challenging part is to wrap all this into 3D. Here are a few resources about this technique:

Some 2D code in JavaScript: http://codepen.io/DonKarlssonSan/pen/BopXpq
The toxiclibs collection also provide algorithms for DLA: http://toxiclibs.org/2010/02/new-package-simutils/
Here's more information and some 3D code as well: http://paulbourke.net/fractals/dla/
Same site, but in 3D (you can even buy a software there): http://paulbourke.net/fractals/dla3d/
More 2D code here: http://formandcode.com/code-examples/simulate-dla

Maybe this is some inspiration for you, but maybe you know all these links already

Best,
Thomas

Thanks for the reply. I've found a paper where they describe the algorithm used, but I've still have found no way/recipes to replicate a convincing cellular replication using daemons or trying to find a software that can export at least an obj where to start working. It's very similar to a explosions, can realflow also simulate "pyros" ? Every suggestion is very welcome
