3D diffusion limited aggregation

Diffusion Limited Aggregation system

An implementation of Diffusion Limited Aggregation systems that can be rendered by using povray or can be explored interactively by using a dead simple viewer.

Povray

It's possible to save the DLA system as a pov file ready to be rendered with povray. Here's an example to render 10 millions particles on a 4K canvas.

$ cargo run --release -- -p 10000000 -a 8 -g 30 -s povray
$ povray +A +W4096 +H4096 dla.pov

Interactive JS viewer

It's also possible to dump the state of the DLA system as a plain JS file that can be used to power great web visualizations. An example viewer is provided and here's an example on how to explore a system made of 10K particles.

$ cargo run --release -- -p 10000 -a 8 -g 30 -s js
$ firefox index.html

Raw CSV dump

In case you want to render the system by yourself then feel free to use the csv scene format to save the cells in the DLA system. As an example, take a look at how I can render it with Buzz, my ray tracer.

$ cargo run --release -- -p 10000 -a 8 -g 30 -s csv
$ cd ../r3d && cargo run --release --example particles < dla/dla.csv
