It's from June, but I haven't seen this before...
...and was wondering if some of you might be interested.
Have a nice weekend! o/

We present a new, numerically stable algorithm that allows us to compute a previouslyinfeasible, fractalized Stanford Bunny composed of 10 billion triangles. Recent work [Kim
2015] showed that it is feasible to compute quaternion Julia sets that conform to any arbitrary
shape. However, the scalability of the technique was limited because it used high-order rationals requiring 80 bits of precision. We address the sources of numerical difficulty and allow
the same computation to be performed using 64 bits. Crucially, this enables computation on
the GPU, and computing a 10-billion-triangle model now takes 17 days instead of 10 years.
Oh .... uh ..... I guess it's in the wrong section.
Haven't been lurking here for years. YEARS. OMG. -.-
My sorries.

I believe this guy was involved in writing the paper: https://www.youtube.com/watch?v=LPMhX8PKNEk
Pretty cool effect, future horror movies will be trippy.

But is it fluffy?
How many parameters does this warped Julia set have? I don't quite get the approach.
When they've gotten it down from years to days ...
... does it also scale from hours to real-time?
