FWIW, I should have the code for this ready tonight. Four C++ files, that use the Cairo graphics lib along with the GLM library:
http://cairographics.org/
http://glm.g-truc.net/0.9.7/index.html
It creates the attached rendering in around 2.5 seconds on my piece of shi% laptop with an I3... ;^) The resolution is 1024x1024. I am busy adding comments to the crude code.
BTW, thank you +Juaquin Anderson for making me think of applying my existing field code to growing DLA clusters in the first place! :^D
Also, thank you +Roger Bagula for giving me hints on how to make better, clearer, renderings wrt granularity. :^)
The DLA is in white, and the field is plotted in red...
;^)

Roger BagulaOwnerThat picture is nice!Apr 30, 2016- Roger BagulaOwnerDLA isn't a vacuum thing:
you need a fluid and a charged particle mostly.
The charged particles are diffusing through the discrete fluid medium.
If the vacuum at small enough scale were discrete,
A DLA might work: scale 10^/(32) cm...very very small.Apr 30, 2016 - Roger BagulaOwnerA recent article:

DLA may be a real process, but I usually think of it as the computer algorithm involving a random walk and a connected cluster.
The computer algorithm doesn't involve a field calculation, but the probability distribution of the random Walker involves the field from the cluster. It's tricky to explain, but the field is part of the process of conventional DLAApr 30, 2016

Yup. When I try to simulate a real process, I notice myself adding stuff that does not belong there. I play the role as creator a bit too much. This is bad. For instance, I made up the reset algorithm. Even though it produces new growth, and increases density on the inner branches, is it real? IMHO, Na, I came up with it on the fly. :^o
Following a field with discrete steps, well I hope those steps are of Plank length, or the simulation is total crap...
lol. ;^)May 9, 2016- +Chris Thomasson
Everything is made up, but some things you make up are actually elegantly made up. ;-)May 9, 2016
