Some math based art (diffused limited aggregation)

[capnrob97]

These are diffused limited aggregation simulations (just running on 1 ARM core, will work on getting them parallelized to the Epiphany next)

A member on another forum has done some interesting stuff with this and working on some speed ups.

I will see if I can get him to start posting here.

I am still going to try for each eCore to handle 1 particle for a 16x speedup, just need work to stop taking all my time

[capnrob97]

I have a version now that uses all 16 eCores on a board.

Run time ~35 seconds for 32,000 particles vs 3:30-4:00 minutes on a single ARM core.

Still room for improvement I am sure.

80,000 particles

Hey, I finally found one thread.

The DLA is about as tight as it can get, with the framebuffer reads/writes being the slowest part.

Got the fast approximation of sin() and cos() going, slashed the runtime for 32,000 particles down from ~35 seconds down to 20 - 21 seconds, huge improvement.

That's great! Once finished, will this be on github, and maybe part of the parallella-examples?

It makes for very cool art.

Wife sent these to snapfish to get printed, just got them in the mail.

Printed on nice photo paper.

Will frame and hang in the office or somewhere.

Probably going to be the first framed art created on a parallella.
