  Author here, I also made a small post on the three.js discourse with a little more background: https://discourse.threejs.org/t/map33-js-v0-1-a-library-to-b...

  By the way you can add missing tiles by double clicking on the grid. Auto-loading everything as you move can be hard on some computers / phones.

  Anyone wanting a more mature library for 3d maps, https://deck.gl/ is pretty good and made by Uber.

  Nice, reminds me of this demo from a few years back: https://blog.mapbox.com/bringing-3d-terrain-to-the-browser-w...

  Nice work! Had a go at modifying an existing library to display bathymetry data a little while ago, tried writing about it. https://vulkd.com/articles/3d-underwater-maps/ Some hyperlinks there which could be of interest.

  It should be fairly simple to display a linestring from a gpx file or similar to the map, just write a method to convert x/y/z coords to lng/lat/alt

  Any plans on adding support for displaying GIS data? I would love something like this I could drop a point, line or polygon onto!

  Opened this on a 3 year old iPhone 8 and it loaded quickly and generated super smooth 60 FPS renders. Looks great!

  Lovely work!

  I can imagine a game based on this where you get dropped somewhere on Earth and your score is based on how few double clicks to load new tiles it takes you to recognise where you are.

  Nice pretty demo. It's for a software engineering consultancy?

  Thanks for the demo, it's pretty cool to see how fast a detailed map can be rendered outside google maps.

  Looks cool! Is there a way to export the mesh & the texture?
