So... we've been building a client+cloud GPU accelerated visual analytics stack for a couple years now, including a distributed variant of their composable layers notion, so if this is exciting to you, please check out our jobs page at www.graphistry.com :) We stay away from GIS in favor of more event analysis problems, but many of the same problems and techniques apply.

(Uber's team is wonderful too, so if you want a bigger company experience, would highly endorse them as well!)

I get 14 fps on their top example. New macbook pro. And this is supposed to be ready?

Their shader is doing software 64 bit float emulation, including trignometric functions.

That city graphic is really precise.

(edit: it looks like the 64 bit math is used only for the map projection part of the shader... so it's not quite as ridiculous as it might seem, my haswell system is limited by CPU, not by vertex shader performance)

Crashes both IE11 and Chrome 54 for me.

Doesn't crash FF 48, but damn it locks up the system for maybe 20s.

They have a megashader with an entire 64 bit float emulation library, which takes a good while to compile.

I can't help but roll my eyes whenever I see more WebGL visualizations from Uber. I had interviewed there maybe a year ago for the visualizations team, but didn't get an offer because I "had too much WebGL experience and not enough d3 experience." I think this is now the second or third webgl based library since released by Uber.

You may have applied before the WebGL frameworks team was set up.
