But it'd be nicer with earth's rotational axis staying in the same place.
In app.js, switching from THREE.TrackballControls to THREE.OrbitControls will make it behave like this:
before commenting. These are quite impressive.
How much work did this one
How would you rate the difficulty of doing something similar with:
* clicking areas brings a popover for more info
* from PostGIS latlong polygons for, say, France's regions (and maybe hierarchical subdivisions)
* replacing polygons by ones with finer details as a region is being zoomed on
* coloring the regions according to a choosable statistic
* Not familiar with the data set you mention but so long as it's mostly documented it should be okay.
* I've never tackled the idea of a hierarchal map even with vectors so I don't know - with the right data, the bit I'm most concern about is the transition from one data set to the next.
* Coloring regions is straightforward
I don't have spare time to do it but am happy to help if you get stuck.
> the bit I'm most concern about is the transition from one data set to the next.
Yep. I have dabbled a tiny amount with three.js; my understanding is that there would be at least some kind of lag, as a new geometry is inserted into the pipeline. I don't know about trying to transition a mesh into another one.

Damn, I was not expecting that you would even ponder doing it. You seem like such a nice person.
The context of my asking is a for professional project where some visualization could help in selling it. Customers love the shiny. If I go on doing it, I'll let you know!
1. Can you put two separate opacity controls for the base map and the Voronoi regions? I like the appearance of the original better than anything I could configure with this single opacity slider.
2. A lot of regions meet at the north and south poles. That's something that the original doesn't have, so I'd guess that's an artifact of numerical errors.
Point 2 is the main thing to fix. I think it's because I don't have a concept of wrapping when I generate the cells initially.
Thanks for the feedback.
However it doesn't seem that your cells are using geodesics, so it's probably not on the surface.
Thanks to the transparency of the globe I noticed this when @MereInterest pointed out the 0 0 coordinates of several airports.
By the way if you can find a way to add the airport call letters to the cell when clicked that would be amazing.
Excited to work on that tonight when my daughter goes to sleep :)
I made a small error in my explanation for the date line: I meant to say "voronoi border with the cells just to the west" (instead of east)
By the way if you have a list of the 0 0 coordinate airports, I can do a best effort search for their correct location. Let me know,
FF 60.0.2 on Win7
FWIW I see the same issue on the latest Chrome on MacOS. Maybe the cell boundary lines are ending up _just_ inside the globe's surface, and it's close enough that it ends up looking a little different on everybody's machine?
If that is the case, maybe a simple "tweak the radius of the Earth" dial might do the job :-)
Maybe it's not working?
Most web browser maps translate my Mac's trackpad scroll events to zoom actions. Infuriating.
Only Apple's new MapKitJS does not do this.
I thought to make workaround using GreaseMonkey overrides, or whatever people do these days, but I don't do frontend stuff so would have start from scratch.
Maybe someone else has a better idea.
Here, the points are airports. There was a related discussion yesterday about a similar project.
