Just discovered https://giro3d.org/, looks awesome and really reminds me of a discussion several years ago with @erilem 🙃
@oguyot_c2c We already have support for a subset of the 3dtiles spec (pnts and b3dm). You can find pnts demo on giro3d website. b3dm, the best I have is this video: https://vimeo.com/335095397. I plan on adding demos on the website soon.
And I'm currently working on support for meshes from WFS sources, including extrusion. Teaser, currently it looks like this: https://i.imgur.com/J13jlDY.jpg . This should land soon I think.
